Freezing or solidification is a phase change in which a liquid turns into a solid when its temperature is lowered below its freezing point. The reverse process is melting.

All known liquids, except liquid helium, freeze when the temperature is lowered enough. Liquid helium remains liquid at atmospheric pressure even at absolute zero, and can be solidified only under pressure.^[1] For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid–liquid transition temperatures. For example, agar displays a hysteresis in its melting and freezing temperatures. It melts at 85 °C (185 °F) and solidifies from 31 °C to 40 °C (89.6 °F to 104 °F).

Crystallization[link]

Most liquids freeze by crystallization, formation of crystalline solid from the uniform liquid. This is a first-order thermodynamic phase transition, which means that, as long as solid and liquid coexist, the equilibrium temperature of the system remains constant and equal to the melting point. Crystallization consists of two major events, nucleation and crystal growth. Nucleation is the step wherein the molecules start to gather into clusters, on the nanometer scale, arranging in a defined and periodic manner that defines the crystal structure. The crystal growth is the subsequent growth of the nuclei that succeed in achieving the critical cluster size.

Supercooling[link]

In spite of the second law of thermodynamics, crystallization of pure liquids usually begins at a lower temperature than the melting point, due to high activation energy of homogeneous nucleation. The creation of a nucleus implies the formation of an interface at the boundaries of the new phase. Some energy is expended to form this interface, based on the surface energy of each phase. If a hypothetical nucleus is too small, the energy that would be released by forming its volume is not enough to create its surface, and nucleation does not proceed. Freezing does not start until the temperature is low enough to provide enough energy to form stable nuclei. In presence of irregularities on the surface of the containing vessel, solid or gaseous impurities, pre-formed solid crystals, or other nucleators, heterogeneous nucleation may occur, where some energy is released by the partial destruction of the previous interface, raising the supercooling point to be near or equal to the melting point. The melting point of water at 1 atmosphere of pressure is very close to 0 °C (32 °F, 273.15 K), and in the presence of nucleating substances the freezing point of water is close to the melting point, but in the absence of nucleators water can super cool to −40 °C (−40 °F, 233 K) before freezing.^[2][3][4] Under high pressure (2,000 atmospheres) water will super cool to as low as −70 °C (−94 °F, 203 K) before freezing.^[5]

Exothermicity[link]

Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure is released. This is often seen as counter-intuitive,^[6] since the temperature of the material does not rise during freezing, except if the liquid were supercooled. But this can be understood, since heat must be continually removed from the freezing liquid or the freezing process will stop. The energy released upon freezing is a latent heat, and is known as the enthalpy of fusion and is exactly the same as the energy required to melt the same amount of the solid.

Low-temperature helium is the only known exception to the general rule.^[7] Helium-3 has a negative enthalpy of fusion at temperatures below 0.3 K. Helium-4 also has a very slightly negative enthalpy of fusion below 0.8 K. This means that, at appropriate constant pressures, heat must be added to these substances in order to freeze them.^[8]

Vitrification[link]

Certain materials, such as glass and glycerol, may harden without crystallizing; these are called amorphous solids. Amorphous materials as well as some polymers do not have a true freezing point, as there is no abrupt phase change at any specific temperature. Instead, there is a gradual change in their viscoelastic properties over a range of temperatures. Such materials are characterized by a glass transition that occurs at a glass transition temperature, which may be roughly defined as the "knee" point of the material's density vs. temperature graph.

Freezing of living organisms[link]

Many living organisms are able to tolerate prolonged periods of time at temperatures below the freezing point of water. Most living organisms accumulate cryoprotectants such as anti-nucleating proteins, polyols, and glucose to protect themselves against frost damage by sharp ice crystals. Most plants, in particular, can safely reach temperatures of −4 °C to −12 °C. Certain bacteria, notably Pseudomonas syringae, produce specialized proteins that serve as potent ice nucleators, which they use to force ice formation on the surface of various fruits and plants at about −2 °C.^[9] The freezing causes injuries in the epithelia and makes the nutrients in the underlying plant tissues available to the bacteria.^[10]

Bacteria[link]

Three species of bacteria, Carnobacterium pleistocenium, as well as Chryseobacterium greenlandensis and Herminiimonas glaciei, have reportedly been revived after surviving for thousands of years frozen in ice.

Plants[link]

Many plants undergo a process called hardening, which allows them to survive temperatures below 0 °C for weeks to months.

Animals[link]

The nematode Haemonchus contortus can survive 44 weeks frozen at liquid nitrogen temperatures. Other nematodes that survive at temperatures below 0 °C include Trichostrongylus colubriformis and Panagrolaimus davidi. Many species of reptiles and amphibians survive freezing. See cryobiology for a full discussion.

Human gametes and 2-, 4- and 8-cell embryos can survive freezing and are viable for up to 10 years, a process known as cryopreservation.

Experimental attempts to freeze human beings for later revival are known as cryonics.

Food preservation[link]

Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacterial growth.

Philip Glass (born January 31, 1937) is an American composer. One of the highest profile composers writing "classical" music today, he is often said to be one of the most influential composers of the late 20th century.^[1][2][3] His music is also often controversially described as minimalist, along with the work of the other "major minimalists" La Monte Young, Terry Riley and Steve Reich.^[4]

He has lately distanced himself from the "minimalist" label, describing himself instead as a composer of "music with repetitive structures."^[5] Though his early mature music shares much with what is normally called "minimalist", he has since evolved stylistically.^[6][7] Currently, he describes himself as a "Classicist", pointing out that he is trained in harmony and counterpoint and studied such composers as Franz Schubert, Johann Sebastian Bach and Wolfgang Amadeus Mozart with Nadia Boulanger.^[8]

Glass is a prolific composer: he has written works for the musical group which he founded, the Philip Glass Ensemble (with which he still performs on keyboards), as well as operas, musical theatre works, ten symphonies, eleven concertos, solo works, chamber music including string quartets and instrumental sonatas, and film scores. Three of his film scores have been nominated for Academy Awards.

Glass counts many artists among his friends and collaborators, including visual artists (Richard Serra, Chuck Close), writers (Doris Lessing, David Henry Hwang, Allen Ginsberg), film and theatre directors (including Errol Morris, Robert Wilson, JoAnne Akalaitis, Godfrey Reggio, Paul Schrader, Martin Scorsese, Christopher Hampton, Bernard Rose, and many others), choreographers (Lucinda Childs, Jerome Robbins, Twyla Tharp), and musicians and composers (Ravi Shankar, David Byrne, the conductor Dennis Russell Davies, Foday Musa Suso, Laurie Anderson, Linda Ronstadt, Paul Simon, Joan LaBarbara, Arthur Russell, David Bowie, Brian Eno, Roberto Carnevale, Patti Smith, Aphex Twin, Lisa Bielawa, Andrew Shapiro, John Moran, Bryce Dessner and Nico Muhly). Among recent collaborators are Glass's fellow New Yorker Woody Allen, Stephen Colbert,^[9] and poet and songwriter Leonard Cohen.

Life and work[link]

For a list of works, see List of compositions by Philip Glass

Beginnings, early education and influences (1937–1964)[link]

Glass was born on January 31, 1937, in Baltimore, Maryland,^[10][11] the son of Ida (née Gouline) and Benjamin Charles Glass,^[12] and the grandson of Jewish immigrants from Lithuania.^[13] His father owned a record store, and consequently Glass's record collection consisted to a large extent of unsold records, including modern music (such as Hindemith, Bartók, Schoenberg,^[14] Shostakovich) and Western classical music (including Ludwig van Beethoven's String Quartets and Schubert's B♭ Piano Trio, which he cites as a "big influence"),^[15] at a very early age. He then studied the flute as a child at the Peabody Conservatory of Music and entered an accelerated college program at the University of Chicago at the age of 15, where he studied Mathematics and Philosophy. In Chicago he discovered the serialism of Webern and composed a twelve-tone string trio.^[16] In 1954 Glass went to Paris for the first time, encountering the films of Jean Cocteau, which made a lasting impression on him. He visited artists' studios and saw their work; "the bohemian life you see in [Cocteau's] Orphée was the life I ... was attracted to, and those were the people I hung out with."^[17]

Glass then went on to the Juilliard School of Music where the keyboard became his main instrument. His composition teachers included Vincent Persichetti and William Bergsma, while fellow students included Steve Reich. During this time, in 1959, he was a winner in the BMI Foundation's BMI Student Composer Awards, one of the most prestigious international prizes for young composers. In the summer of 1960, he studied with Darius Milhaud at the summer school of the Aspen Music Festival and composed a Violin Concerto for a fellow student, Dorothy Pixley-Rothschild.^[18] After leaving Juilliard in 1962, Glass moved to Pittsburgh and worked as a school-based composer-in-residence in the public school system, composing various choral, chamber and orchestral music.^[19]

Paris (1964–1966)[link]

In 1964, Glass received a Fulbright Scholarship and went to Paris, where he studied with the eminent composition teacher Nadia Boulanger from autumn of 1964 to summer of 1966. Glass's years in Paris as a student made a lasting impression and influenced his work ever since, as the composer admitted in 1979: "The composers I studied with Boulanger are the people I still think about most—Bach and Mozart."^[20]

Glass later stated in his autobiography Music by Philip Glass (1987) that the new music performed at Pierre Boulez's Domaine Musical concerts in Paris lacked any excitement for him (with the notable exceptions of music by John Cage and Morton Feldman), but he was deeply impressed by new films and theatre performances. He encountered revolutionary films of the French New Wave, such as those of Jean-Luc Godard and François Truffaut, which ignored the rules set by an older generation of artists.,^[21] and Glass made friends with American visual artists (the sculptor Richard Serra and his wife Nancy Graves),^[22] actors and directors (JoAnne Akalaitis, Ruth Maleczech, David Warrilow, and Lee Breuer, with whom Glass later founded the experimental theatre group Mabou Mines). Together with Akalaitis (they married in 1965), Glass in turn attended performances by theatre groups including Jean-Louis Barrault's Odéon theatre, The Living Theatre and the Berliner Ensemble in 1964 to 1965.^[23] These significant encounters resulted in a collaboration with Breuer for which Glass contributed music for a 1965 staging of Samuel Beckett's Comédie (Play, 1963). The resulting piece (written for two soprano saxophones) was directly influenced by the play's open-ended, repetitive and almost musical structure and was the first one of a series of four early pieces in a minimalist, yet still dissonant, idiom.^[16] After Play, Glass also acted in 1966 as music director of a Breuer production of Brecht's Mother Courage and Her Children, featuring the theatre score by Paul Dessau.

In parallel with his early excursions in experimental theatre, Glass worked in winter 1965 and spring 1966 as a music director and composer^[24] on a film score (Chappaqua, Conrad Rooks, 1966) with Ravi Shankar and Alla Rakha, which added another important influence on Glass's musical thinking. His distinctive style arose from his work with Shankar and Rakha and their perception of rhythm in Indian music as being entirely additive. He renounced all his compositions in a moderately modern style resembling Milhaud's, Aaron Copland's, and Samuel Barber's, and began writing pieces based on repetitive structures of Indian music and a sense of time influenced by Samuel Beckett: a piece for two actresses and chamber ensemble, a work for chamber ensemble and his first numbered string quartet (No.1, 1966).^[25]

Glass then left Paris for northern India in 1966, where he came in contact with Tibetan refugees and began to gravitate towards Buddhism. He met Tenzin Gyatso, the 14th Dalai Lama, in 1972, and has been a strong supporter of the Tibetan independence ever since.

[edit] Minimalism: From Strung Out to Music in 12 Parts (1967–1974)

SoHo, New York City

Shortly after arriving in New York City in March 1967, Glass attended a performance of works by Steve Reich (including the ground-breaking minimalist piece Piano Phase), which left a deep impression on him; he simplified his style and turned to a radical "consonant vocabulary".^[16] Finding little sympathy from traditional performers and performance spaces, Glass eventually formed an ensemble with fellow ex-students Steve Reich, Jon Gibson, and others, and began performing mainly in art galleries and studio lofts of SoHo. The visual artist Richard Serra provided Glass with Gallery contacts, while both collaborated on various sculptures, films and installations; from 1971 to 1974 he became Serra's regular studio assistant.^[22][26]

Between summer of 1967 and the end of 1968, Glass composed nine works, including Strung Out (for amplified solo violin, composed in summer of 1967), Gradus (for solo saxophone, 1968), Music in the Shape of a Square (for two flutes, composed in May 1968, an homage to Erik Satie), How Now (for solo piano, 1968) and 1+1 (for amplified tabletop, November 1968) which were "clearly designed to experiment more fully with his new-found minimalist approach".^[27] The first concert of Glass's new music was at Jonas Mekas's Film-Makers Cinemathèque (Anthology Film Archives) in September 1968. This concert included the first work of this series with Strung Out (performed by the violinist Pixley-Rothschild) and Music in the Shape of a Square (performed by Glass and Gibson). The musical scores were tacked on the wall, and the performers had to move while playing. Glass's new works met with a very enthusiastic response by the audience which consisted mainly of visual and performance artists who were highly sympathetic to Glass's reductive approach.

Apart from his music career, Glass had a moving company with his cousin, the sculptor Jene Highstein, and worked as a plumber and cab driver (in 1973 to 1978). During this time he made friends with other New York based artists such as Sol LeWitt, Nancy Graves, Michael Snow, Bruce Nauman, Laurie Anderson, and Chuck Close, who created a now famous portrait of Glass.^[28] (Glass returned the favour in 2005 with A Musical Portrait of Chuck Close for piano.)

With 1+1 and Two Pages (composed in February 1969) Glass turned to a more "rigorous approach" to his "most basic minimalist technique, additive process",^[29] pieces which were followed in the same year by Music in Contrary Motion and Music in Fifths (a kind of homage to his composition teacher Nadia Boulanger, who pointed out "hidden fifths" in his works but regarded them as cardinal sins). Eventually Glass's music grew less austere, becoming more complex and dramatic, with pieces such as Music in Similar Motion (1969), and Music with Changing Parts (1970). These pieces were performed by The Philip Glass Ensemble in the Whitney Museum of American Art in 1969 and in the Solomon R. Guggenheim Museum in 1970, often encountering hostile reaction from critics,;^[16] but Glass's music was also met with enthusiasm from younger artists such as Brian Eno and David Bowie (at the Royal College of Art ca. 1970).^[30] Eno described this encounter with Glass's music as one of the "most extraordinary musical experiences of [his] life", as a "viscous bath of pure, thick energy", concluding "this was actually the most detailed music I'd ever heard. It was all intricacy, exotic harmonics".^[31] In 1970 Glass returned to the theatre, composing music for the theatre group Mabou Mines, resulting in his first minimalist pieces employing voices: Red Horse Animation and Music for Voices (both 1970, and premiered at the Paula Cooper Gallery).^[32]

After differences of opinion with Steve Reich in 1971,^[16] Glass formed the Philip Glass Ensemble (while Reich formed Steve Reich and Musicians), an amplified ensemble including keyboards, wind instruments (saxophones, flutes), and soprano voices.

Glass's music for his ensemble culminated in the four-hour-long Music in Twelve Parts (1971–1974), which began as a single piece with twelve instrumental parts but developed into a cycle that summed up Glass's musical achievement since 1967, and even transcended it – the last part features a twelve-tone theme, sung by the soprano voice of the ensemble. "I had broken the rules of modernism and so I thought it was time to break some of my own rules", according to Glass.^[33] Though he finds the term minimalist inaccurate to describe his later work, Glass does accept this term for pieces up to and including Music in 12 Parts, excepting this last part which "was the end of minimalism" for Glass. As he pointed out: "I had worked for eight or nine years inventing a system, and now I'd written through it and come out the other end."^[33]

Another Look at Harmony: The Portrait Trilogy (1975–1979)[link]

Glass continued his work with a series of instrumental works, called Another Look at Harmony (1975–1977). For Glass this series demonstrated a new start, hence the title: "What I was looking for was a way of combining harmonic progression with the rhythmic structure I had been developing, to produce a new overall structure. (...) I'd taken everything out with my early works and it was now time to decide just what I wanted to put in—a process that would occupy me for several years to come."^[33] Parts 1 and 2 of "Another Look at Harmony" were included in a collaboration with Robert Wilson, a piece of musical theater that was later designated by Glass as the first opera of his portrait opera trilogy: Einstein on the Beach. Composed in Spring to Fall of 1975 in close collaboration with Wilson, Glass's first opera was first premiered in summer 1976 at the Festival d'Avignon, and in November of the same year to a mixed and partly enthusiastic reaction from the audience at the Metropolitan Opera in New York City. Scored for the Philip Glass Ensemble, solo violin, chorus, and featuring actors (reciting texts by Christopher Knowles, Lucinda Childs and Samuel M. Johnson), Glass's and Wilson's essentially plotless opera was conceived as a "metaphorical look at Albert Einstein: scientist, humanist, amateur musician—and the man whose theories (...) led to the splitting of the atom", evoking nuclear holocaust in the climactic scene, as critic Tim Page pointed out.^[34] As with Another Look at Harmony, "Einstein added a new functional harmony that set it apart from the early conceptual works".^[34] Composer Tom Johnson came to the same conclusion, comparing the solo violin music to Johann Sebastian Bach, and the "organ figures (...) to those Alberti basses Mozart loved so much".^[35] The piece was praised by the Washington Post as "one of the seminal artworks of the century."

Einstein on the Beach was followed by further music for projects by the theatre group Mabou Mines such as Dressed like an Egg (1975), and again music for plays and adaptations from prose by Samuel Beckett, such as The Lost Ones (1975), Cascando (1975), Mercier and Camier (1979). Glass also turned to other media; two multi-movement instrumental works for the Philip Glass Ensemble originated as music for film and TV: North Star (1977 for the Documentary "Mark di Suvero, sculptor" by Francois de Menil and Barbara Rose) and four short cues for Jim Henson's TV-series for children, Sesame Street, named Geometry of Circles (1979).

Another series, Fourth Series (1977–79), included music for chorus and organ ("Part One", 1977), organ and piano ("Part Two" and "Part Four", 1979), and music for a radio adaption of Constance DeJong's novel Modern Love ("Part Three", 1978). Part Two and Part Four were used (and hence renamed) in two dance productions by choreographer Lucinda Childs (who had already contributed to and performed in Einstein on the Beach). "Part Two" was included in Dance (a collaboration with visual artist Sol LeWitt, 1979), and "Part Four" was renamed as Mad Rush, and performed by Glass on several occasions such as the first public appearance of the 14th Dalai Lama in New York City in Fall 1981. The piece demonstrates Glass's turn to more traditional models: the composer added a conclusion to an open-structured piece which "can be interpreted as a sign that he [had] abandoned the radical non-narrative, undramatic approaches of his early period", as the pianist Steffen Schleiermacher points out.^[36]

In Spring 1978, Glass received a commission from the Netherlands Opera (as well as a Rockefeller Foundation grant) which "marked the end of his need to earn money from non-musical employment."^[37] With the commission Glass continued his work in music theater, composing his opera Satyagraha (composed in 1978–1979, premiered in 1980 at Rotterdam), based on the early life of Mahatma Gandhi in South Africa, Rabindranath Tagore, and Martin Luther King Jr.. For Satyagraha , Glass worked in close collaboration with two "SoHo friends": the writer Constance deJong, who provided the libretto, and the set designer Robert Israel. This piece was in other ways a turning point for Glass, as it was his first work since 1963 scored for symphony orchestra, even if the most prominent parts were still reserved for solo voices and chorus. Shortly after completing the score in August 1979, Glass met the conductor Dennis Russell Davies, who he helped prepare for performances in Germany (using a piano-four-hands version of the score); together they started to plan another opera, to be premiered at the Stuttgart State Opera.^[21]

Completing the Portrait Trilogy: Akhnaten and beyond (1980–1986)[link]

While planning a third part of his "Portrait Trilogy", Glass turned to smaller music theatre projects such as the non-narrative Madrigal Opera (for six voices and violin and viola, 1980), and The Photographer, a biographic study on the photographer Eadweard Muybridge (1982). Glass also continued to write for the orchestra with his most famous film score to date, Koyaanisqatsi (Godfrey Reggio, 1981–1982). Some pieces which were not used in the film (such as Facades) eventually appeared on the album Glassworks (1982, CBS Records), which brought Glass's music to a wider public.

The "Portrait Trilogy" was completed with Akhnaten (1982–1983, premiered in 1984), a vocal and orchestral composition sung in Akkadian, Biblical Hebrew, and Ancient Egyptian. In addition, this opera featured an actor reciting ancient Egyptian texts in the language of the audience. Akhnaten was commissioned by the Stuttgart Opera in a production designed by Achim Freyer. It premiered simultaneously at the Houston Opera in a production directed by David Freeman and designed by Peter Sellars. At the time of the commission, the Stuttgart Opera House was undergoing renovation, necessitating the use of a nearby playhouse with a smaller orchestra pit. Upon learning this, Glass and conductor Dennis Russell Davies visited the playhouse, placing music stands around the pit to determine how many players the pit could accommodate. The two found that they could not fit a full orchestra in the pit. Glass decided to eliminate the violins, which had the effect of "giving the orchestra a low, dark sound that came to characterize the piece and suited the subject very well."^[21] As Glass remarked in 1992, Akhnaten is significant in his work since it represents a "first extension out of a triadic harmonic language", an experiment with the polytonality of his teachers Persichetti and Milhaud, a musical technique which Glass compares to "an optical illusion, such as in the paintings of Josef Albers".^[38]

Glass again collaborated with Robert Wilson on another opera, the CIVIL warS (1983, premiered in 1984), which also functioned as the final part ("the Rome section) of Wilson's epic work by the same name, originally planned for an "international arts festival that would accompany the Olympic Games in Los Angeles".^[39] (Glass also composed a highly prestigious work for chorus and orchestra for the opening of the Games, The Olympian: Lighting of the Torch and Closing ). The premiere of The CIVIL warS in Los Angeles never materialized and the opera was in the end premiered at the Opera of Rome. Glass's and Wilson's opera includes musical settings of Latin texts by the 1st-century-Roman playwright Seneca and allusions to the music of Giuseppe Verdi and from the American Civil War, featuring the 19th century figures Giuseppe Garibaldi and Robert E. Lee as characters.

In the mid-1980s, Glass produced "works in different media at an extraordinarily rapid pace".^[40] Projects from that period include music for dance (Dance Pieces, Jerome Robbins, 1983, and In the Upper Room, Twyla Tharp, 1986), and music for theatre productions Endgame (1984), and Company (1983). Beckett vehemently disapproved of the production of Endgame at the American Repertory Theater (Cambridge, Massachusetts), which featured Joanne Akalaitis's direction and Glass's Prelude for timpani and double bass, but in the end, he authorized the music for Company, four short, intimate pieces for string quartet that were played in the intervals of the dramatization. This composition was initially regarded by the composer as a piece of Gebrauchsmusik ('music for use')—"like salt and pepper (...) just something for the table”, as he noted.^[41] Eventually Company was published as Glass's String Quartet No.2 and in a version for string orchestra, being performed by ensembles ranging from student orchestras to renowned ones such as the Kronos Quartet and the Kremerata Baltica.

This interest in writing for the string quartet and the string orchestra led to a chamber and orchestral film score for Mishima: A Life in Four Chapters (Paul Schrader, 1984–85), which Glass recently described as his "musical turning point" that developed his "technique of film scoring in a very special way".^[42]

Glass also dedicated himself to vocal works with two sets of songs, Three Songs for chorus (1984, settings of poems by Leonard Cohen, Octavio Paz and Raymond Levesque), and a song cycle initiated by CBS Masterworks Records: Songs from Liquid Days (1985), with texts by songwriters such as David Byrne, Paul Simon, in which the Kronos Quartet is featured (as it is in Mishima) in a prominent role. Glass also continued his series of operas with adaptations from literary texts such as The Juniper Tree (an opera collaboration with composer Robert Moran, 1984), Edgar Allan Poe's The Fall of the House of Usher (1987), and also worked with novelist Doris Lessing on the opera The Making Of The Representative For Planet 8 (1985–86, and performed by the Houston Grand Opera and English National Opera in 1988).

Operas and the turn to symphonic music (1987–1991)[link]

Compositions such as Company, Facades and String Quartet No.3 (the last two extracted from the scores to Koyaanisqatsi and Mishima) gave way to a series of works more accessible to ensembles such as the string quartet and symphony orchestra, in this returning to the structural roots of his student days. In taking this direction his chamber and orchestral works were also written in a more and more traditional and lyrical style. In these works, Glass often employs old musical forms such as the chaconne and the passacaglia – for instance in Satyagraha,^[16] the Violin Concerto No. 1 (1987), Symphony No. 3 (1995), Echorus (1995) and also recent works such as Symphony No. 8 (2005),^[43] and Songs and Poems for Solo Cello (2006).

A series of orchestral works that were originally composed for the concert hall commenced with the 3-movement Violin Concerto No. 1 (1987). This work was commissioned by the American Composers Orchestra and written for and in close collaboration with the violinist Paul Zukofsky and the conductor Dennis Russel Davies, who since then has encouraged the composer to write numerous orchestral pieces. The Concerto is dedicated to the memory of Glass's father: "His favorite form was the violin concerto, and so I grew up listening to the Mendelssohn, the Paganini, the Brahms concertos. (...) So when I decided to write a violin concerto, I wanted to write one that my father would have liked."^[44] Among its multiple recordings, in 1992, the Concerto was performed and recorded by Gidon Kremer and the Vienna Philharmonic Orchestra. This turn to orchestral music was continued with a symphonic trilogy of "portraits of nature", commissioned by the Cleveland Orchestra, the Rotterdam Philharmonic Orchestra, and the Atlanta Symphony Orchestra: The Light (1987), The Canyon (1988), and Itaipu (1989).

While composing for symphonic ensembles, Glass also composed music for piano, with the cycle of five movements titled Metamorphosis (adapted from music for a theatrical adaptation of Franz Kafka's The Metamorphosis, and for the Errol Morris film The Thin Blue Line, 1988]). In the same year Glass met the poet Allen Ginsberg by chance in a book store in the East Village of New York City, and they immediately "decided on the spot to do something together, reached for one of Allen's books and chose Wichita Vortex Sutra",^[45] a piece for reciter and piano which in turn developed into a music theatre piece for singers and ensemble, Hydrogen Jukebox (1990).

Glass also turned to chamber music; he composed two String Quartets (No.4 and No.5, for the Kronos Quartet, 1989 and 1991), and chamber works which originated as incidental music for plays, such as Music from "The Screens" (1989/1990). This work originated in one of many theater music collaborations with the director Joanne Akalaitis, who originally asked the Gambian musician Foday Musa Suso "to do the score [for Jean Genet's "The Screens"] in collaboration with a western composer".^[46] Glass had already collaborated with Suso in the film score to Powaqqatsi (Godfrey Reggio, 1986). Music from "The Screens" is on occasion a touring piece for Glass and Suso, and individual pieces found its way to the repertoire of Glass and the cellist Wendy Sutter. Another collaboration was a collaborative recording project with Ravi Shankar, initiated by Peter Baumann (a member of the band Tangerine Dream), which resulted in the album Passages (1990).

In the late 1980s and early 1990s, Glass's projects also included two highly prestigious opera commissions, based on the life of two explorers, Christopher Columbus (The Voyage [1990], commissioned by the Metropolitan Opera, with a libretto by David Henry Hwang), and Vasco da Gama (White Raven) [1991], a collaboration with Robert Wilson and composed for the opening of the Expo '98). Especially in The Voyage, the composer "explore[d] new territory", with its "newly arching lyricism", "Sibelian starkness and sweep", and "dark, brooding tone (...) a reflection of its increasingly chromatic (and dissonant) palette", as one commentator put it.^[16]

The Cocteau Trilogy and Symphonies (1991–1996)[link]

After these operas, Glass began working on a symphonic cycle, commissioned by the conductor Dennis Russell Davies, who told Glass at the time: "I'm not going to let you . . . be one of those opera composers who never write a symphony".^[47] Glass responded with two 3-movement symphonies ("Low" [1992], and Symphony No. 2 [1994]); his first in an ongoing series of symphonies is a combination of the composer's own musical material with themes featured in prominent tracks of the David Bowie/ Brian Eno album Low (1977),^[48] whereas Symphony No.2 is described by Glass as a study in polytonality. He referred to the music of Honegger, Milhaud, and Villa-Lobos as possible models for his symphony.^[49] With the Concerto Grosso (1992), Symphony No. 3 (1995), a Concerto for Saxophone Quartet and Orchestra (1995), written for the Rascher Quartet (all commissioned by conductor Dennis Russel Davies), and Echorus (1994/95), a more transparent, refined, and intimate chamber-orchestral style paralleled the excursions of his large-scale symphonic pieces. In the four movements of his Third Symphony, Glass treats a 19-piece string orchestra as an extended chamber ensemble. In the third movement, Glass re-uses the chaconne as a formal device; one commentator characterized Glass's symphony as one of the composer's "most tautly unified works"^[50][51] The third Symphony was closely followed by a fourth, subtitled Heroes (1996), commissioned the American Composers Orchestra. Its six movements are symphonic reworkings of themes by Glass, David Bowie, and Brian Eno (from their album "Heroes", 1977); as in other works by the composer, it is also a hybrid work and exists in two versions: one for the concert hall, and another, shorter one for dance, choreographed by Twyla Tharp.

1993 in Florence

Another commission by Dennis Russell Davies was a second series for piano, the Etudes for Piano (dedicated to Davies as well as the production designer Achim Freyer); the complete first set of ten Etudes has been recorded and performed by Glass himself. Bruce Brubaker and Dennis Russell Davies have each recorded the original set of six. Most of the Etudes are composed in the post-minimalist and increasingly lyrical style of the times: "Within the framework of a concise form, Glass explores possible sonorities ranging from typically Baroque passagework to Romantically tinged moods".^[52] Some of the pieces also appeared in different versions such as in the theatre music to Robert Wilson's Persephone (1994, commissioned by the Relache Ensemble) or Echorus (a version of Etude No.2 for two violins and string orchestra, written for Edna Mitchell and Yehudi Menuhin 1995).

Glass's prolific output in the 1990s continued to include operas with an opera triptych (1991–1996), which the composer described as an "homage" to writer and film director Jean Cocteau, based on his prose and cinematic work: Orphée (1949), La Belle et la Bête (1946), and the novel Les Enfants Terribles (1929, later made into a film by Cocteau and Jean-Pierre Melville, 1950). In the same way the triptych is also a musical homage to the work of the group of French composers associated with Cocteau, Les Six (and especially to Glass's teacher Darius Milhaud), as well as to various 18th century composers such as Gluck and Bach whose music featured as an essential part of the films by Cocteau.

The inspiration of the first part of the trilogy, Orphée (composed in 1991, and premiered in 1993 at the American Repertory Theatre) can be conceptually and musically traced to Gluck's opera Orfeo ed Euridice (Orphée et Euridyce, 1762/1774),^[16] which had a prominent part in Cocteau's 1949 film Orphee.^[53] One theme of the opera, the death of Eurydice, has some similarity to the composer's personal life: the opera was composed after the unexpected death in 1991 of Glass's wife, artist Candy Jernigan: "(...) One can only suspect that Orpheus' grief must have resembled the composer's own", K. Robert Schwartz suggests.^[16] The opera's "transparency of texture, a subtlety of instrumental color, (...) a newly expressive and unfettered vocal writing"^[16] was praised, and The Guardian's critic remarked "Glass has a real affinity for the French text and sets the words eloquently, underpinning them with delicately patterned instrumental textures".^[54]

For the second opera, La Belle et la Bête (1994, scored for either the Philip Glass Ensemble or a more conventional chamber orchestra), Glass replaced the soundtrack (including Georges Auric's film music) of Cocteau's film, wrote "a new fully operatic score and synchronize[d] it with the film".^[55] The final part of the triptych returned again to a more traditional setting with the "Dance Opera" Les Enfants Terribles (1996), scored for voices, three pianos and dancers, with choreography by Susan Marshall. The characters are depicted by both singers and dancers. The scoring of the opera evokes Bach's Concerto for Four Harpsichords, but in another way also "the snow, which falls relentlessly throughout the opera (...) bearing witness to the unfolding events. Here time stands still. There is only music, and the movement of children through space" (Glass).^[56][57]

Symphonies, opera, and concertos (1997–2004)[link]

In the late 1990s and early 2000s, Glass's lyrical and romantic styles peaked with numerous projects: operas, theatre and film scores (Martin Scorsese's Kundun, 1997, Godfrey Reggio's Naqoyqatsi, 2002, and Stephen Daldry's The Hours, 2002), a series of five concerti, and three symphonies centered on orchestra-singer and orchestra-chorus interplay. Two symphonies, Symphony No.5 "Choral" (1999) and Symphony No.7 "Toltec" (2004), and the song cycle Songs of Milarepa (1997) are thematically meditative. The operatic Symphony No.6 Plutonian Ode (2002) for soprano and orchestra was commissioned by the Brucknerhaus, Linz, and Carnegie Hall in celebration of Glass's sixty-fifth birthday, and originated as Glass's collaboration with Allen Ginsberg (poet, piano – Ginsberg, Glass), based on his eponymous poem.

Besides writing for the concert hall, Glass continued his ongoing operatic series with adaptions from literary texts: The Marriages of Zones 3, 4 and 5 ([1997] story-libretto by Doris Lessing), In the Penal Colony (2000, after the novella by Franz Kafka), and the chamber opera The Sound of a Voice (2003, with David Henry Hwang), which features the Pipa, performed by Wu Man at its premiere. Glass also collaborated again with the co-author of Einstein on the Beach, Robert Wilson, on Monsters of Grace (1998), and created a biographic opera on the life of astronomer Galileo Galilei (2001).

In the early 2000s, Glass started a series of five concerti with the Tirol Concerto for Piano and Orchestra (2000, premiered by Dennis Russell Davies as conductor and soloist), and the Concerto Fantasy for Two Timpanists and Orchestra (2000, for the timpanist Jonathan Haas). The Concerto for Cello and Orchestra (2001) had its premiere performance in Beijing, featuring cellist Julian Lloyd Webber; it was composed in celebration of his fiftieth birthday.^[58] These concertos were followed by the concise and rigorously neo-baroque Concerto for Harpsichord and Orchestra (2002), demonstrating in its transparent, chamber orchestral textures Glass's classical technique, evocative in the "improvisatory chords" of its beginning a toccata of Froberger or Frescobaldi, and 18th century music.^[59] Two years later, the concerti series continued with Piano Concerto No. 2: After Lewis and Clark (2004), composed for the pianist Paul Barnes. The concerto celebrates the pioneers' trek across North America, and the second movement features a duet for piano and Native American flute. With the chamber opera The Sound of a Voice, Glass's Piano Concerto No. 2 might be regarded as bridging his traditional compositions and his more popular excursions to World Music, also found in Orion (also composed in 2004).

[edit] Songs and Poems (2005–2007)

Philip Glass in December 2007

Waiting for the Barbarians, an opera from J. M. Coetzee's novel (with the libretto by Christopher Hampton), had its premiere performance in September 2005. Glass defined the work as a "social/political opera", as a critique on the Bush administration's war in Iraq, a "dialogue about political crisis", and an illustration of the "power of art to turn our attention toward the human dimension of history".^[60] While the opera's themes are Imperialism, apartheid, and torture, the composer chose an understated approach by using "very simple means, and the orchestration is very clear and very traditional; it's almost classical in sound", as the conductor D. Russell Davies notes.^[61][62]

Two months after the premiere of this opera, in November 2005, Glass's Symphony No.8, commissioned by the Bruckner Orchester Linz, was premiered at the Brooklyn Academy of Music in New York City. After three symphonies for voices and orchestra, this piece was a return to purely orchestral and abstract composition; like previous works written for the conductor Dennis Russell Davies (the 1992 Concerto Grosso and the 1995 Symphony No.3), it features extended solo writing. Critic Allan Kozinn described the symphony's chromaticism as more extreme, more fluid, and its themes and textures as continually changing, morphing without repetition, and praised the symphony's "unpredictable orchestration", pointing out the "beautiful flute and harp variation in the melancholy second movement".^[63] Alex Ross, remarked that "against all odds, this work succeeds in adding something certifiably new to the overstuffed annals of the classical symphony. (...) The musical material is cut from familiar fabric, but it’s striking that the composer forgoes the expected bustling conclusion and instead delves into a mood of deepening twilight and unending night."^[64]

The Passion of Ramakrishna (2006), was composed for the Pacific Symphony Orchestra, the Pacific Chorale and the conductor Carl St. Clair. The 45 minutes choral work is based on the writings of Indian Spiritual leader Sri Ramakrishna, which seem "to have genuinely inspired and revived the composer out of his old formulas to write something fresh", as one critic remarked, whereas another noted that "The musical style breaks little new ground for Glass, except for the glorious Handelian ending (...) the "composer’s style ideally fits the devotional text".^[65][66]

A Cello Suite, composed for the cellist Wendy Sutter, "Songs and Poems for Solo Cello" (2005–2007), was equally lauded by critics. It was described by Lisa Hirsch as "a major work, (...) a major addition to the cello repertory" and "deeply Romantic in spirit, and at the same time deeply Baroque".^[67] Another critic, Anne Midgette of the Washington Post, noted that the suite "maintains an unusual degree of directness and warmth"; she also noted a kinship to a major work by Johann Sebastian Bach: "Digging into the lower registers of the instrument, it takes flight in handfuls of notes, now gentle, now impassioned, variously evoking the minor-mode keening of klezmer music and the interior meditations of Bach's cello suites".^[68] Glass himself pointed out that "in many ways it owes more to Schubert than to Bach".^[69]

In 2007, Glass also worked alongside Leonard Cohen on an adaptation of Cohen's poetry collection Book of Longing. The work, which premiered in June 2007 in Toronto, is a piece for seven instruments and a vocal quartet, and contains recorded spoken word performances by Cohen and imagery from his collection.

Appomattox, an opera surrounding the events at the end of the American Civil War, was commissioned by the San Francisco Opera and premiered on October 5, 2007. As in Waiting for the Barbarians, Glass collaborated with the writer Christopher Hampton, and as with the preceding opera and Symphony No.8, the piece was conducted by Glass's long-time collaborator Dennis Russell Davies, who noted that "in his recent operas the bass line has taken on an increasing prominence,(...) (an) increasing use of melodic elements in the deep register, in the contrabass, the contrabassoon—he's increasingly using these sounds and these textures can be derived from using these instruments in different combinations. (...) He's definitely developed more skill as an orchestrator, in his ability to conceive melodies and harmonic structures for specific instrumental groups. (...) what he gives them to play is very organic and idiomatic."^[62]

Apart from this large-scale opera, Glass added a work to his catalogue of theater music in 2007, and continuing—after a gap of twenty years—to write music for the dramatic work of Samuel Beckett. He provided a "hypnotic" original score for a compilation of Beckett's short plays Act Without Words I, Act Without Words II, Rough for Theatre I and Eh Joe, directed by JoAnne Akalaitis and premiered in December 2007. Glass's work for this production was described by The New York Times as "icy, repetitive music that comes closest to piercing the heart".^[70]

Chamber music, concertos and symphonies (2008–present)[link]

2008 to 2010 Glass continued to work on a series of chamber music pieces which started with "Songs and Poems": the Four Movements for Two Pianos (2008, premiered by Dennis Davies and Maki Namekawa in July 2008), a Sonata for Violin and Piano composed in "the Brahms tradition" (completed in 2008, premiered by violinist Maria Bachman and pianist Jon Klibonoff in February 2009); a String sextet (an adaption of the Symphony No.3 of 1995 made by Glass's musical director Michael Riesman) followed in 2009. Pendulum (2010, a one-movement piece for violin and piano), a second Suite of cello pieces for Wendy Sutter (2011), and Partita for solo violin for violinist Tim Fain (2010, first performance of the complete work 2011), are recent entries in the series.^[71]

Glass performing Book of Longing in Milan, September 2008

Other works for the theater were a score for Euripides' The Bacchae (2009, directed by JoAnne Akalaitis), and Kepler (2009), yet another operatic biography of a scientist or explorer. The opera is based on the life of 17th century astronomer Johannes Kepler, against the background of the Thirty Years' War, with a libretto compiled from Kepler's texts and poems by his contemporary Andreas Gryphius. It is Glass's first opera in German, and was premiered by the Bruckner Orchester Linz and Dennis Russell Davies in September 2009. LA Times critic Mark Swed and others described the work as "oratorio-like"; Swed pointed out that the work is Glass's "most chromatic, complex, psychological score" and that the "The orchestra dominates (...) I was struck by the muted, glowing colors, the character of many orchestral solos and the poignant emphasis on bass instruments".^[72]

In 2009 and 2010, Glass returned to the concerto genre. Violin Concerto No. 2 in four movements was commissioned by violinist Robert McDuffie, and subtitled "The American Four Seasons" (2009), as an homage to Vivaldi's set of concertos "Le quattro stagioni". It premiered in December 2009 by the Toronto Symphony Orchestra, and was subsequently performed by the London Philharmonic Orchestra in April 2010.^[73] The Double Concerto for Violin and Cello and Orchestra (2010) was composed for soloists Maria Bachmann and Wendy Sutter and also as a ballet score for the Nederlands Dans Theater.^[74][75] Other orchestral projects of 2010 are short orchestral scores for films; to a multimedia presentation based on the novel Icarus at the Edge of Time by theoretical physicist Brian Greene, which premiered on June 6, 2010, and the score for the Brazilian film Nosso Lar (released in Brazil on September 3, 2010). Glass also donated a short work, Brazil, to the video game Chime, which was released on February 3, 2010.

In January 2011, Glass performed at the MONA FOMA festival in Hobart, Tasmania. The festival promotes a broad range of art forms, including experimental sound, noise, dance, theatre, visual art, performance and new media.^[76]

In August 2011, Glass presented a series of music, dance, and theater performances as part of the Days and Nights Festival.^[77] Along with the Philip Glass Ensemble, scheduled performers include Molissa Fenley and Dancers, John Moran with Saori Tsukada, as well as a screening of Dracula with Glass's score.^[78] Glass hopes to present this festival annually, with a focus on art, science, and conservation.^[79]

Glass's recently completed and projected works include Symphony No.9 (2010–2011), Symphony No.10 (2011), Cello Concerto No.2 (2012, based on the film score to Naqoyqatsi), Symphony No.11, String Quartet No.6, and the operas The Lost (2011–2012)^[80] and The Perfect American (2011).^[81] Glass's Ninth Symphony was co-commissioned by the Bruckner Orchester Linz, the American Composers Orchestra and the Los Angeles Philharmonic Orchestra. The symphony's first performance took place on January 1, 2012 at the Brucknerhaus in Linz, Austria (Dennis Russell Davies conducting the Bruckner Orchester Linz); the American premiere was on January 31, 2012 (Glass's 75th birthday), at Carnegie Hall (Dennis Russell Davies conducting the American Composers Orchestra), and the West Coast premiere with the Los Angeles Philharmonic under the baton of John Adams on April 5.^{[82] [83][84][85][86]} The Lost is based on a play by Austrian playwright and novelist Peter Handke, Die Spuren der Verirrten (2006). It will be premiered in 2013 in Linz (Austria), conducted by Dennis Russell Davies and directed by David Pountney, who pointed out that the English translation of the original German title means "traces of those who lost their way": "[So] not knowing where you are going, let alone where you came from, seems to be a pre-condition. It is also, perhaps, the way we are? Philip’s music is perfect for this kind of abstraction".^[87] The Perfect American was composed in 2011 to a commission from Teatro Real Madrid.^[88] The libretto is based on a book of the same name by Peter Stephan Jungk and covers the final months of the life of Walt Disney.^[81] The world premiere is scheduled for Teatro Real Madrid on 22 January 2013 with British baritone Christopher Purves taking the role of Disney.^[81] The UK premiere is scheduled for the English National Opera at the London Coliseum later in 2013.^[89]

On December 1, 2011 Glass, together with Lou Reed and Laurie Anderson, joined the Occupy Wall Street protests at the Lincoln Center, reciting from the libretto of his opera Satyagraha (1978–79), which had the final performance on the same evening.^[90] A Website dedicated to Occupy Wall Street points out that "it is no doubt timely that Philip Glass's opera 'Satyagraha'—which depicts Gandhi's early struggle against colonial oppression in India—should be revived by the Metropolitan Opera in 2011, a year which has seen popular revolutions in North Africa, mass uprisings in Europe, and the emergence of Occupy Wall Street protests in the United States. (...) we see a glaring contradiction in ‘Satyagraha’ being performed at the Lincoln Center where in recent weeks protestors from Occupy Wall Street have been arrested and forcibly removed for exercising their First Amendment rights to peaceful public assembly."^[91] And as the composer states: "Unfortunately, there's always a good time to do this opera. It's just the way it is. But never has it been so close at hand (...) My position is that this is free speech and free assembly. (...) And what these people do by acting in this way, they bring back to us the importance of our basic freedoms."^[92]

Influences and connections[link]

Aside from composing in the Western classical tradition, his music has ties to rock, ambient music, electronic music, and world music. Early admirers of his minimalism include musicians Brian Eno and David Bowie.^[93] In the 1990s, Glass composed the aforementioned symphonies Low (1992) and Heroes (1996), thematically derived from the Bowie-Eno collaboration albums Low and "Heroes" (composed in late 1970s Berlin).

Glass has collaborated with recording artists such as Paul Simon, Suzanne Vega,^[94] Mick Jagger,^[95] Leonard Cohen, David Byrne, Uakti, Natalie Merchant,^[96] and Aphex Twin (yielding an orchestration of Icct Hedral in 1995 on the Donkey Rhubarb EP). Glass's compositional influence extends to musicians such as Mike Oldfield (who included parts from Glass's North Star in Platinum), and bands such as Tangerine Dream and Talking Heads. Glass and his sound designer Kurt Munkacsi produced the American post-punk/new wave band Polyrock (1978 to the mid-1980s), as well as the recording of John Moran's The Manson Family (An Opera) in 1991, which featured punk legend Iggy Pop, and a second (unreleased) recording of Moran's work featuring poet Allen Ginsberg.

In 1970, Glass and Klaus Kertess (owner of the Bykert Gallery) formed a record label named Chatham Square Productions (named after the location of the studio of a Philip Glass Ensemble member Dick Landry).^[21] In 1993 Glass formed another record label, Point Music; in 1997, Point Music released Music for Airports, a live, instrumental version of Eno's composition of the same name, by Bang on a Can All-Stars. In 2002, Glass and his producer Kurt Munkacsi and artist Don Christensen founded the Orange Mountain Music company, dedicated to "establishing the recording legacy of Philip Glass" and, to date, have released sixty albums of Glass's music.

Music for film[link]

Glass has composed many film scores, starting with the orchestral score for Koyaanisqatsi (1982), and continuing with two biopics, Mishima: A Life in Four Chapters (1985, resulting in the String Quartet No.3) and Kundun (1997) about the Dalai Lama, for which he received his first Academy Award nomination.

The year after scoring Hamburger Hill (1987), Glass began a collaboration with the filmmaker Errol Morris with his music for Morris's celebrated documentary The Thin Blue Line. He continued composing for the Qatsi trilogy with the scores for Powaqqatsi (1988) and Naqoyqatsi (2002). In 1995 he composed the theme for Reggio's short independent film Evidence. He even made a cameo appearance in Peter Weir's The Truman Show (1998), which uses music from Powaqqatsi, Anima Mundi and Mishima, as well as three original tracks by Glass (who is actually briefly visible performing at the piano in the film itself). In the 1990s, he also composed scores for Bent' (1997) and the thriller Candyman (1992) and its sequel, Candyman: Farewell to the Flesh (1995), plus a film adaptation of Joseph Conrad's The Secret Agent (1996).

In 1999, he finished a new soundtrack for the 1931 film Dracula. The Hours (2002) earned him a second Academy Award nomination, and was followed by another Morris documentary, The Fog of War (2003). In the mid-2000s Glass provided the scores to films such as Secret Window (2004), Neverwas (2005), The Illusionist and Notes on a Scandal, garnering his third Academy Award nomination for the latter. Glass's most recent film scores include No Reservations (Glass makes a brief cameo in the film sitting at an outdoor cafe), Cassandra's Dream (2007), Les Regrets (2009), Mr Nice (2010) and the Brazilian film Nosso Lar (2010). In 2009 Glass composed original theme music for Transcendent Man about the life and ideas of Ray Kurzweil by filmmaker Barry Ptolemy.

In the 2000s Glass's work from the 1980s again became known to wider public through various media. In 2005 his Concerto for Violin and Orchestra (1987) was featured in the surreal French thriller, La Moustache, providing a tone intentionally incongruous to the banality of the movie's plot.^[97] Metamorphosis for Piano (1988) was featured in the reimagined Battlestar Galactica in the episode "Valley of Darkness", and in 2008, Rockstar Games released Grand Theft Auto IV featuring Glass's "Pruit Igoe" (from Koyaanisqatsi). "Pruit Igoe" and "Prophecies" (also from Koyaanisqatsi) were used both in a trailer for Watchmen and in the film itself. Watchmen also included two other Glass pieces in the score: "Something She Has To Do" (from The Hours) and "Protest (Act II Scene 3)" (from Satyagraha).

In 2011, it was confirmed that Glass is scoring for South Korean director Park Chan-wook's Hollywood debut film Stoker.^[98]

Personal life[link]

Glass describes himself as "a Jewish-Taoist-Hindu-Toltec-Buddhist",^[14] and he is a supporter of Tibetan independence. In 1987 he co-founded the Tibet House with Columbia University professor Robert Thurman and the actor Richard Gere. Glass is a vegetarian.^[99]

Glass has four children and one granddaughter. Juliet (b. 1968) and Zachary (b. 1971) are his children from his first marriage, to theater director JoAnne Akalaitis (married 1965, divorced 1980). Granddaughter Zuri (b.1989) is Zachary's daughter. His second marriage to Luba Burtyk was dissolved. His third wife, the artist Candy Jernigan, died of liver cancer in 1991, aged 39. Marlowe and Cameron are Glass's sons with his fourth wife, Holly Critchlow (from whom Glass is divorced). Glass lives in New York and in Cape Breton, Nova Scotia. He has been romantically involved with cellist Wendy Sutter since 2005.^[100]

Glass is the first cousin once removed of Ira Glass, host of the nationally syndicated radio show This American Life. Ira interviewed Glass onstage at Chicago's Field Museum; this interview was broadcast on NPR's Fresh Air. Ira interviewed Glass a second time at a fundraiser for St. Ann's Warehouse; this interview was given away to public radio listeners as a pledge drive thank you gift in 2010. Ira and Glass recorded a version of the composition Glass wrote to accompany his friend Allen Ginsberg's poem "Wichita Vortex Sutra." Glass's cousin is Ira Glass's father.^[101]

According to an interview, Franz Schubert is Glass's favorite composer.^[102]

Mr. Freeze (surname pronounced "freeze", based on the German pronunciation) is a fictional character, a DC Comics supervillain who is an enemy of Batman. Created by Bob Kane, he first appeared in Batman #121 (February 1959).^[1]

Freeze is a scientist who must wear a cryogenic suit in order to survive, and bases his crimes around a "cold" or "ice" theme, complete with a "cold gun" that freezes its targets solid. In the most common variation of his origin story, he is a former cryogenics expert who suffered an industrial accident while attempting to cure his terminally ill wife, Nora.

In the original Batman television series, Mr. Freeze was played in various episodes by George Sanders, Otto Preminger and Eli Wallach. He was voiced in Batman: The Animated Series by Michael Ansara, and by Clancy Brown in The Batman. In the 1997 film, Batman & Robin, he was portrayed by Arnold Schwarzenegger.

IGN's list of the Top 100 Comic Book Villains of All Time List ranked Mr. Freeze as #67.^[2]
