A CD-R (Compact Disc-Recordable) is a variation of the Compact Disc invented by Philips and Sony. CD-R is a Write Once Read Many (WORM) optical medium, although the whole disk does not have to be entirely written in the same session.

CD-R retains a high level of compatibility with standard CD readers, unlike CD-RW which can be re-written, but is not capable of playing on many readers.

History[link]

Assorted CD-Rs

The CD-R, originally named CD Write-Once (WO), specification was first published in 1988 by Philips and Sony in the 'Orange Book'. The Orange Book consists of several parts, furnishing details of the CD-WO, CD-MO (Magneto-Optic), and CD-RW (ReWritable). The latest editions have abandoned the use of the term "CD-WO" in favor of "CD-R", while "CD-MO" were very little used. Written CD-Rs and CD-RWs are, from a technical standpoint, fully compatible with the Audio CD (Red Book) and CD-ROM (Yellow Book) standards, although some hardware compatible with Red Book CDs may have difficulty reading CD-Rs and especially CD-RWs. They use Eight-to-Fourteen Modulation, CIRC error correction plus the third error correction layer defined for CD-ROM.

CD-R recording systems available in 1990 were similar to the washing machine-sized Meridian CD Publisher, based on the two-piece rack mount Yamaha PDS audio recorder costing $35,000, not including the required external ECC circuitry for data encoding, SCSI hard drive subsystem, and MS-DOS control computer. By 1992 the cost of typical recorders was down to $10–12,000, and in September 1995 Hewlett-Packard introduced its model 4020i manufactured by Philips, which at $995 was the first recorder to cost less than $1000.^[1]

The dye materials developed by Taiyo Yuden made it possible for CD-R discs to be compatible with Audio CD and CD-ROM discs.

Initially in the United States, there was a market separation between "music" CD-Rs and "data" CD-Rs, the former being several times more expensive than the latter due to industry copyright arrangements with the RIAA.^[2] Physically, there is no difference between the discs save for the Disc Application Flag that identifies their type: standalone audio recorders will only accept "music" CD-Rs to enforce the RIAA arrangement, while computer CD-R drives can use either type of media to burn either type of content.^[3]

Physical characteristics[link]

A standard CD-R is a 1.2 mm (0.047 in) thick disc made of polycarbonate with a 120 mm (4.7 in) or 80 mm (3.150 in) diameter. The 120 mm disc has a storage capacity of 74 minutes of audio or 650 Megabytes of data. CD-R/RWs are available with capacities of 80 minutes of audio or 737,280,000 bytes (700 MB), which they achieve by molding the disc at the tightest allowable tolerances specified in the Orange Book CD-R/CD-RW standards. The engineering margin that was reserved for manufacturing tolerance has been used for data capacity instead, leaving no tolerance for manufacturing; for these discs to be truly compliant with the Orange Book standard, the manufacturing process must be perfect^{[citation needed]}.

Despite the foregoing, most CD-Rs on the market have an 80 minute capacity. There are also 90 minute/790 MB and 99 minute/870 MB discs, although they are less common (and depart from the Orange Book standard outright). Also, due to the limitations of the data structures in the ATIP (see below), 90 and 99 minute blanks will identify as 80 minute ones. (As the ATIP is part of the Orange Book standard, it is natural that its design does not support some nonstandard disc configurations.) Therefore, in order to use the additional capacity, these discs have to be burned using "overburn" options in the CD recording software. (Overburning itself is so named because it is outside the written standards, but, due to market demand, it has nonetheless become a de facto standard function in most CD writing drives and software for them.)

Some drives use special techniques, such as Plextor's GigaRec or Sanyo's HD-BURN, to write more data onto a given disc; these techniques are inherently deviations from the Compact Disc (Red, Yellow, and/or Orange Book) standards, making the recorded discs proprietary-formatted and not fully compatible with standard CD players and drives. However, in certain applications where discs will not be distributed or exchanged outside a private group and will not be archived for a long time, a proprietary format may be an acceptable way to obtain greater capacity (up to 1.2 GB with GigaRec or 1.8 GB with HD-BURN on 99 minute media). The greatest risk in using such a proprietary data storage format, assuming that it works reliably as designed, is that it may be difficult or impossible to repair or replace the hardware used to read the media if it fails, is damaged, or is lost after its original vendor discontinues it.

Nothing in the Red, Yellow or Orange Book standards prohibits disc reading/writing devices from having the capacity to read or write discs beyond the Compact Disc standards. The standards do require discs to meet precise requirements in order to be called Compact Discs, but the other discs may be called by other names; if this were not true, no DVD drive could legally bear the Compact Disc logo. While disc players and drives may have capabilities beyond the standards, enabling them to read and write nonstandard discs, there is no assurance, in the absence of explicit additional manufacturer specifications beyond normal Compact Disc logo certification, that any particular player or drive will perform beyond the standards at all or consistently. Furthermore, if the same device with no explicit performance specs beyond the Compact Disc logo initially handles nonstandard discs reliably, there is no assurance that it will not later stop doing so, and in that case, there is no assurance that it can be made to do so again by service or adjustment. Therefore, discs with capacities larger than 650 MB, and especially those larger than 700 MB, are less interchangeable among players/drives than standard discs and are not very suitable for archival use, as their readability on future equipment, or even on the same equipment at a future time, is not assured, even under the assumption that the discs will not degrade at all.

Photomicrograph of the groove in a CD-R disc

The polycarbonate disc contains a spiral groove, called the "pregroove" (because it is molded in before data are written to the disc), to guide the laser beam upon writing and reading information. The pregroove is molded into the top side of the polycarbonate disc, where the pits and lands would be molded if it were a pressed (nonrecordable) Red Book CD; the bottom side, which faces the laser beam in the player or drive, is flat and smooth. The polycarbonate disc is coated on the pregroove side with a very thin layer of organic dye. Then, on top of the dye is coated a thin, reflecting layer of silver, a silver alloy, or gold. Finally, a protective coating of a photo-polymerizable lacquer is applied on top of the metal reflector and cured with UV-light.

A blank CD-R is not "empty"; the pregroove has a wobble (the ATIP), which helps the writing laser to stay on track and to write the data to the disc at a constant rate. Maintaining a constant rate is essential to ensure proper size and spacing of the pits and lands burned into the dye layer. As well as providing timing information, the ATIP (absolute time in pregroove) is also a data track containing information about the CD-R manufacturer, the dye used and media information (disc length and so on). The pregroove is not destroyed when the data are written to the CD-R, a point which some copy protection schemes use to distinguish copies from an original CD.

There are three basic formulations of dye used in CD-Rs:

1. Cyanine dye CD-Rs were the earliest ones developed, and their formulation is patented by Taiyo Yuden. CD-Rs based on this dye are mostly green in color. The earlier models were very chemically unstable and this made cyanine based discs unsuitable for archival use; they could fade and become unreadable in a few years. Many manufacturers like Taiyo Yuden use proprietary chemical additives to make more stable cyanine discs ("metal stabilized Cyanine", "Super Cyanine"). Older cyanine dye based CD-Rs, as well as all the hybrid dyes based on cyanine, were very sensitive to UV-rays and could have become unreadable after only a few days if they were exposed to direct sunlight. Although the additives used have made cyanine more stable, it is still the most sensitive of the dyes in UV rays (showing signs of degradation within a week of direct sunlight exposure). A common mistake users make is to leave the CD-Rs with the "clear" (recording) surface upwards, in order to protect it from scratches, as this lets the sun hit the recording surface directly.
2. Phthalocyanine dye CD-Rs are usually silver, gold or light green. The patents on phthalocyanine CD-Rs are held by Mitsui and Ciba Specialty Chemicals. Phthalocyanine is a natively stable dye (has no need for stabilizers) and CD-Rs based on this are often given a rated lifetime of hundreds of years. Unlike cyanine, phthalocyanine is more resistant to UV rays and CD-Rs based on this dye show signs of degradation only after two weeks of direct sunlight exposure. However, phthalocyanine is more sensitive than cyanine to writing laser power calibration, meaning that the power level used by the writing laser has to be more accurately adjusted for the disc in order to get a good recording; this may erode the benefits of dye stability, as marginally written discs (with higher correctable error rates) will lose data (i.e. have uncorrectable errors) after less dye degradation than well written discs (with lower correctable error rates).
3. Azo dye CD-Rs are dark blue in color, and their formulation is patented by Mitsubishi Chemical Corporation. Azo dye is also chemically stable, and Azo CD-Rs are typically rated with a lifetime of decades. Azo is the most resistant dye against UV rays and begins to degrade only after the third or fourth week of direct sunlight exposure. More modern implementations of this kind of dye include Super Azo which is not as deep blue as the earlier Metal Azo. This change of composition was necessary in order to achieve faster writing speeds.

There are many hybrid variations of the dye formulations, such as Formazan by Kodak (a hybrid of cyanine and phthalocyanine).

Unfortunately, many manufacturers have added additional coloring to disguise their unstable cyanine CD-Rs in the past, so the formulation of a disc cannot be determined based purely on its color. Similarly, a gold reflective layer does not guarantee use of phthalocyanine dye. The quality of the disc is also not only dependent on the dye used, it is also influenced by sealing, the top layer, the reflective layer, and the polycarbonate. Simply choosing a disc based on its dye type may be problematic. Furthermore, correct power calibration of the laser in the writer, as well as correct timing of the laser pulses, stable disc speed, and so on., is critical to not only the immediate readability but the longevity of the recorded disc, so for archiving it is important to have not only a high quality disc but a high quality writer. In fact, a high quality writer may produce adequate results with medium quality media, but high quality media cannot compensate for a mediocre writer, and discs written by such a writer cannot achieve their maximum potential archival lifetime.

Speed[link]

These times only include the actual optical writing pass over the disc. For most disc recording operations, additional time is used for overhead processes, such as organizing the files and tracks, which adds to the theoretical minimum total time required to produce a disc. (An exception might be making a disk from a prepared ISO image, for which the overhead would likely be trivial.) At the lowest write speeds, this overhead takes so much less time than the actual disc writing pass that it may be negligible, but at higher write speeds, the overhead time becomes a larger proportion of the overall time taken to produce a finished disc and may add significantly to it.

Also, above 20X speed, drives use a Zoned-CLV or CAV strategy, where the advertised maximum speed is only reached near the outer rim of the disc.^[4] This is not taken into account by the above table. (If this were not done, the faster rotation that would be required at the inner tracks could cause the disc to fracture and/or could cause excessive vibration which would make accurate and successful writing impossible.)

Writing methods[link]

This unreferenced section requires citations to ensure verifiability.

The blank disc has a pre-groove track onto which the data are written. The pre-groove track, which also contains timing information, ensures that the recorder follows the same spiral path as a conventional CD. A CD recorder writes data to a CD-R disc by pulsing its laser to heat areas of the organic dye layer. The writing process does not produce indentations (pits); instead, the heat permanently changes the optical properties of the dye, changing the reflectivity of those areas. Using a low laser power, so as not to further alter the dye, the disc is read back in the same way as a CD-ROM. However, the reflected light is modulated not by pits, but by the alternating regions of heated and unaltered dye. The change of the intensity of the reflected laser radiation is transformed into an electrical signal, from which the digital information is recovered ("decoded"). Once a section of a CD-R is written, it cannot be erased or rewritten, unlike a CD-RW. A CD-R can be recorded in multiple sessions. A CD recorder can write to a CD-R using several methods including:

1. Disc At Once – the whole CD-R is written in one session with no gaps and the disc is "closed" meaning no more data can be added and the CD-R effectively becomes a standard read-only CD. With no gaps between the tracks the Disc At Once format is useful for "live" audio recordings.
2. Track At Once – data are written to the CD-R one track at a time but the CD is left "open" for further recording at a later stage. It also allows data and audio to reside on the same CD-R.
3. Packet Writing – used to record data to a CD-R in "packets", allowing extra information to be appended to a disc at a later time, or for information on the disc to be made "invisible". In this way, CD-R can emulate CD-RW; however, each time information on the disc is altered, more data has to be written to the disc. There can be compatibility issues with this format and some CD drives.

With careful examination, the written and unwritten areas can be distinguished by the naked eye. CD-Rs are written from the center outwards, so the written area appears as an inner band with slightly different shading.

Expected lifespan[link]

Real-life (not accelerated aging) tests have revealed that some CD-Rs degrade quickly even if stored normally.^[5][6] The quality of a CD-R disc has a large and direct influence on longevity—low quality discs should not be expected to last very long. According to research conducted by J. Perdereau, CD-Rs are expected to have an average life expectancy of 10 years.^[7] Branding isn't a reliable guide to quality, because many brands (major as well as no name) do not manufacture their own discs. Instead they are sourced from different manufacturers of varying quality. For best results, the actual manufacturer and material components of each batch of discs should be verified.

An example of a CD-R burned in 2000 showing dye degradation in 2008. Part of the data on it has been lost.

Burned CD-Rs suffer from material degradation, just like most writable media. CD-R media have an internal layer of dye used to store data. In a CD-RW disc, the recording layer is made of an alloy of silver and other metals—indium, antimony, and tellurium.^[8] In CD-R media, the dye itself can degrade, causing data to become unreadable.

As well as degradation of the dye, failure of a CD-R can be due to the reflective surface. While silver is less expensive and more widely used, it is more prone to oxidation resulting in a non-reflecting surface. Gold on the other hand, although more expensive and no longer widely used, is an inactive material, so gold-based CD-Rs do not suffer from this problem.

Since some users have switched to flash memory for similar applications CD-Rs have served for, degradation of memory is not as detrimental.

Labeling[link]

It is recommended if using adhesive-backed paper labels that the labels be specially made for CD-Rs. An unlabeled CD is well balanced, so that it vibrates only slightly when rotated at high speed. Bad or improperly made labels, or labels applied off-center, unbalance the CD and can cause it to vibrate seriously when it spins, which causes read errors and even risks damaging the drive.^[9]

A professional alternative to CD labels is pre-printed CDs using a 5-color silkscreen or offset press. Many large CD replicators now offer this type of service for .03 per impression.

Using a permanent marker pen is also a common practice. However, solvents from such pens can affect the dye layer.

Disposal[link]

Security risk[link]

Since CD-Rs in general cannot be logically erased to any degree, the disposal of CD-Rs presents a possible security issue if they contain sensitive / private data. Destroying the data requires physically destroying the disc or data layer. Heating the disc in a microwave oven for 10–15 seconds effectively destroys the data layer by causing arcing in the metal reflective layer, but this same arcing may cause damage or excessive wear to the microwave oven. Many office paper shredders are also designed to shred CDs. CD-R discs can otherwise be made unreadable by making a visible scratch on the label, or "paint side" radially with a nail or other sharp object.

Some recent burners support erase operations on -R media (Plextor, LiteOn), by "overwriting" the stored data with strong laser power, although the erased area cannot be overwritten with new data.

Recycling[link]

The polycarbonate material and possible gold or silver in the reflective layer would make CD-Rs highly recyclable. However, the polycarbonate is of very little value and the quantity of precious metals is so small that it is not profitable to recover them.^[10] Consequently, recyclers that accept CD-Rs typically do not offer compensation for donating or transporting the materials.^[11][12] However, the reflective surface of destroyed CD-R can be used to the advantage of MacGyver-like hobbyists,^{[dubious – discuss]} as well as more advanced forms of art that re-coordinate the material for texture usage.

William John Evans, known as Bill Evans (August 16, 1929–September 15, 1980) was an American jazz pianist. His use of impressionist harmony, inventive interpretation of traditional jazz repertoire, and trademark rhythmically independent, "singing" melodic lines influenced a generation of pianists. He is considered by some to be the most influential post-World War II jazz pianist.^[2] Evans had a distinct playing posture in which his neck would often be stooped very low, and his face parallel to the piano.

Evans is an inductee of the Down Beat Jazz Hall of Fame.^[3]

Biography[link]

Early life[link]

Bill Evans was born in Plainfield, New Jersey, United States, to a mother of Rusyn ancestry and a father of Welsh descent.^[4] He received his first musical training at his mother's church. Evans' mother was an amateur pianist with an interest in modern classical composers, and Evans began classical piano lessons at age six. He also became a proficient flautist by age 13 and could play the violin.

At age 12, Evans filled in for his older brother Harry in Buddy Valentino's band.^[5] At this age he was able to interpret classical music, but he couldn't improvise. In the beginning, he played exactly what was written in the sheet, but soon started trying to improvise, while learning about harmonies in the songs and how to alter them. Meanwhile, he was playing dance music (and jazz) at home, in a recording studio he built in his family's basement..^[6] In the late 1940s, Evans played boogie woogie in various New Jersey clubs. He attended Southeastern Louisiana University on a music scholarship, and in 1950 performed Beethoven's Third Piano Concerto on his senior recital there, graduating with a degree in piano performance and teaching. He was also among the founding members of SLU's Delta Omega Chapter of Phi Mu Alpha Sinfonia, and played quarterback for the fraternity's football team, helping them win the school's 1949 intramural tournament.^[6]

Evans's first professional job was with sax player Herbie Fields's band, based in Chicago. During the summer of 1950, the band did a three-month tour backing Billie Holiday, including East Coast appearances at Harlem's Apollo Theater and shows in Philadelphia, Baltimore, and at Washington D.C.'s Howard Theater. In addition to Fields and Evans, the band included trumpeter Jimmy Nottingham, trombonist Frank Rosolino and bassist Jim Aton. Upon its return to Chicago, Evans and Aton worked as a duo in Chicago clubs, often backing singer Lurlean Hunter. Shortly thereafter, Evans received his draft notice and entered the U.S. Army.

After his army service, Evans returned to New York and worked at nightclubs with jazz clarinetist Tony Scott and other leading players. Later, he took postgraduate studies in composition at the Mannes College of Music, where he also mentored younger music students.

1950s[link]

Working in New York in the 1950s, Evans gained recognition as a sideman in traditional and so-called Third Stream jazz groups. During this period he had the opportunity to record in many different contexts with some of the best jazz musicians of the time. Seminal recordings made with composer/theoretician George Russell, including "Concerto for Billy the Kid" and "All About Rosie," are notable for Evans's solo work. Evans also appeared on notable albums by Charles Mingus, Oliver Nelson, Tony Scott, and Art Farmer. In 1956, he made his debut album, New Jazz Conceptions, featuring the original version of "Waltz for Debby," for Riverside Records. Producer Orrin Keepnews was convinced to record the reluctant Evans by a demo tape guitarist Mundell Lowe played to him over the phone.

In 1958, Evans was hired by Miles Davis, becoming the only white member of Davis's famed sextet. Though his time with the band was brief (no more than eight months), it was one of the most fruitful collaborations in the history of jazz, as Evans's introspective approach to improvisation deeply influenced Davis's style. Davis wrote in his autobiography, "Bill had this quiet fire that I loved on piano. The way he approached it, the sound he got, was like crystal notes or sparkling water cascading down from some clear waterfall." Additionally, Davis said, "I've sure learned a lot from Bill Evans. He plays the piano the way it should be played."

Evans's desire to pursue his own projects as a leader (and increasing problems with drug use) led him to leave the Davis sextet in late 1958. Shortly after, he recorded Everybody Digs Bill Evans, documenting the wholly original meditative sound he was exploring at the time. But Evans came back to the sextet at Davis's request to record the jazz classic Kind of Blue in early 1959. Evans's contribution to the album was overlooked for years; in addition to cowriting the song "Blue in Green,"^[7] he had also already developed the ostinato figure from the track "Flamenco Sketches" on the 1958 solo recording "Peace Piece" from his album Everybody Digs Bill Evans. Evans also penned the heralded liner notes for Kind of Blue comparing jazz improvisation to Japanese visual art.^[8] By the fall of 1959, he had started his own trio.

1960s[link]

At the turn of the decade, Evans led a trio with bassist Scott LaFaro and drummer Paul Motian. This group was to become one of the most acclaimed piano trios — and jazz bands in general — of all time. With this group, Evans's focus settled on traditional jazz standards and original compositions, with an added emphasis on interplay among the band members that often bordered on collective improvisation, blurring the line between soloist and accompanist. The collaboration between Evans and the young LaFaro was particularly fruitful, as the two achieved a remarkable level of musical empathy. The trio recorded four albums: Portrait in Jazz (1959); and Explorations, Sunday at the Village Vanguard, and Waltz for Debby, all recorded in 1961. The last two albums are live recordings from the same recording date, and are routinely named among the greatest jazz recordings of all time. In 2005, the full sets were collected on the three-CD set The Complete Village Vanguard Recordings, 1961. There is also a lesser-known recording of this trio, Live at Birdland, taken from radio broadcasts in early 1960, though the sound quality is poor.

In addition to introducing a new freedom of interplay within the piano trio, Evans began (in performances such as "My Foolish Heart" from the Vanguard sessions) to explore extremely slow ballad tempos and quiet volume levels, which had been virtually unknown in jazz. His chordal voicings became more impressionistic, reminiscent of classical composers such as Debussy, Ravel, Scriabin, and Satie, and he moved away from the thick block chords he had often used with Davis. His sparse left-hand voicings supported his lyrical right-hand lines, reflecting the influence of jazz pianist Bud Powell.

Like Davis, Evans was a pioneer of modal jazz, favoring harmonies that helped avoid some of the idioms of bebop and other earlier jazz. In tunes like Time Remembered, the chord changes more or less absorbed the derivative styles of bebop and instead relied on unexpected shifts in color. It was still possible (and desirable) to make these changes swing, and a certain spontaneity appeared in expert solos that were played over the new sound. Most composers refer to the style of Time Remembered as "plateau modal," because of its frequent juxtaposition of harmony.

LaFaro's death at age 25 in a car accident, ten days after the Vanguard performances, devastated Evans. He did not record or perform in public again for several months. His first recording after LaFaro's death was the duet album Undercurrent, with guitarist Jim Hall, released on United Artist Jazz records in 1963. Recorded in two sessions on April 24 and May 14, 1962, it is now widely regarded as a classic jazz piano-guitar duet recording. The album is also notable for its striking cover image, "Weeki Wachee Spring, Florida" by photographer Toni Frissell. The original LP and the first CD reissue featured a cropped, blue-tinted version, overlaid with the title and the Blue Note logo; but for the most recent (24-bit remastered) CD reissue, the image has been restored to its original black-and-white coloration and size, without lettering.

When he re-formed his trio in 1962, Evans replaced LaFaro with bassist Chuck Israels, initially keeping Motian on the drums. Two albums, Moon Beams and How My Heart Sings!, resulted. In 1963, after having switched from Riverside to the much more widely distributed Verve, he recorded Conversations With Myself, an innovative album on which he employed overdubbing, layering up to three individual tracks of piano for each song. The album won him his first Grammy award, for Best Instrumental Jazz Performance — Soloist or Small Group.

Though his time with Verve was prolific in terms of recording, his artistic output was uneven. Despite Israels's fast development and the creativity of new drummer Grady Tate, they were ill-represented by the rather perfunctory album Bill Evans Trio with Symphony Orchestra, with the piece Pavane by Gabriel Fauré remarkably reinvented with improvisations by Evans. Some unique contexts were attempted, such as a big-band live album at Town Hall, recorded but never issued due to Evans's dissatisfaction with it (although the jazz trio portion of the Pavane concert was made into its own somewhat successful release), and an album with a symphony orchestra, not warmly received by critics.

During this time, Helen Keane, Evans's manager, began having an important influence. One of the first women in her field, she significantly helped to maintain the progress (or prevent the deterioration) of Evans's career in spite of his self-destructive lifestyle.

In 1966, Evans discovered the remarkable young Puerto Rican bass player Eddie Gomez. In what turned out to be an eleven-year stay, the sensitive and creative Gomez sparked new developments in both Evans's playing and his trio conception. One of the most significant releases during this period is Bill Evans at the Montreux Jazz Festival, from 1968. Although it was the only album Evans made with drummer Jack DeJohnette, it has remained a critical and fan favorite, due to the trio's remarkable energy and interplay.

Other highlights from this period include "Solo — In Memory of His Father" from Bill Evans at Town Hall (1966), which introduced the famous theme "Turn Out the Stars," a second successful pairing with guitarist Jim Hall; Intermodulation (1966); and the subdued, crystalline solo album Alone (1968), featuring a 14-minute-plus version of "Never Let Me Go." In 1969, Evans visited Ilkka Kuusisto's home in Helsinki and was interviewed about jazz before performing.

1970s[link]

In 1968, Marty Morell joined the trio on drums and remained until 1975, when he retired to family life. This was Evans's most stable, longest-lasting group. Evans had kicked his heroin habit and was entering a period of personal stability as well. The group made several albums, including From Left to Right (1970), which features Evans's first use of electric piano; The Bill Evans Album (1971), which won two Grammies; The Tokyo Concert (1973); Since We Met (1974); and But Beautiful (1974), featuring the trio plus legendary tenor saxophonist Stan Getz in live performances from Holland and Belgium, released posthumously in 1996. Morell was an energetic, straight-ahead drummer, unlike many of the trio's former percussionists, and many critics feel that this was a period of little growth for Evans. After Morell left, Evans and Gomez recorded two duo albums, Intuition and Montreux III.

In 1974, Bill Evans recorded a multimovement jazz concerto specifically written for him by Claus Ogerman entitled Symbiosis, originally released on the MPS Records label. The 1970s also saw Evans collaborate with the singer Tony Bennett on 1975's The Tony Bennett/Bill Evans Album and 1977's Together Again.

On September 13, 1975, Evans's son, Evan, was born. Evan Evans did not often see his always-touring father. A child prodigy, he embarked on a career in film scoring, ambitiously attending college courses in 20th-century composition, instrumentation, and electronic composition at the age of ten. He also studied with many of his father's contemporaries, including Lalo Schifrin and harmony specialist Bernard Maury.

In 1976, Marty Morell was replaced on drums by Eliot Zigmund. Several interesting collaborations followed, and it was not until 1977 that the trio was able to record an album together. Both I Will Say Goodbye (Evans's last album for Fantasy Records) and You Must Believe in Spring (for Warner Bros., released posthumously) highlighted changes that would become significant in the last stage of Evans's career. A greater emphasis was placed on group improvisation and interaction, Evans was reaching new expressive heights in his soloing, and new experiments with harmony and keys were attempted.

Gomez and Zigmund left Evans in 1978. Evans then asked Philly Joe Jones, the drummer he considered his "all-time favorite drummer" and with whom he had recorded his second album in 1957, to fill in. Several bassists were tried, with Michael Moore staying the longest. Evans finally settled on Marc Johnson on bass and Joe LaBarbera on drums. This trio was Evans's last.

Death[link]

Evans was a heroin addict for much of his career, his health was generally poor, and his financial situation worse, for much of the 1960s. By the end of that decade, he appeared to have succeeded in overcoming his addiction to heroin. However, in the late 1970s, cocaine use became a serious problem for Evans. On September 15, 1980, Bill Evans was accompanied by Joe LaBarbera and his partner Laurie Verchomin, to the Mount Sinai Hospital in New York, where he died that afternoon. ^[9] Evans's friend Gene Lees bleakly summarized Evans's struggle with drugs to Peter Pettinger as "the longest suicide in history.".^[6] Bill Evans is buried at Roselawn Memorial Park and Mausoleum, Baton Rouge, East Baton Rouge Parish, Louisiana (Section #161, Plot K), next to his brother Harry Evans, who died the previous year.

Music critic Richard S. Ginell noted, “With the passage of time, Bill Evans has become an entire school unto himself for pianists and a singular mood unto himself for listeners. There is no more influential jazz-oriented pianist—only McCoy Tyner exerts nearly as much pull among younger players and journeymen—and Evans has left his mark on such noted players as: Chick Corea, Herbie Hancock, John McLaughlin, John Taylor, Steve Kuhn, Don Friedman, Marian McPartland, Denny Zeitlin, Bobo Stenson, Warren Bernhardt, Michel Petrucciani and Keith Jarrett, as well as many other musicians worldwide. The music of Bill Evans continues to inspire younger pianists like Fred Hersch, Bill Charlap, Lyle Mays, Eliane Elias^[10] and arguably Brad Mehldau ^[11] early in his career.

Conversations with Myself and Further Conversations with Myself were innovative solo performances involving multiple overdubs of Evans.

Many of his tunes, such as "Waltz for Debby," "Turn Out the Stars," "Very Early," and "Funkallero," have become often-recorded jazz standards. Many tribute recordings featuring his compositions and favorite tunes have been released in the years following his passing as well as tribute compositions. Pat Metheny's "September 15th" is one such recording.

During his lifetime, Evans was honored with 31 Grammy nominations and seven Awards. In 1994, he was posthumously honored with the Grammy Lifetime Achievement Award.
