4′33″ (pronounced "Four minutes, thirty-three seconds") is a three-movement composition by American experimental composer John Cage (1912–1992). It was composed in 1952 for any instrument (or combination of instruments), and the score instructs the performer not to play the instrument during the entire duration of the piece throughout the three movements (which, for the first performance, were divided into thirty seconds for the first, two minutes and twenty-three seconds for the second, and one minute and forty seconds for the third). The piece purports to consist of the sounds of the environment that the listeners hear while it is performed, although it is commonly perceived as "four minutes thirty-three seconds of silence".

4′33″ is Cage's most famous and most controversial composition, and by far the best-known of the numerous musical works that consist mainly of silence.

Conceived around 1947–1948, while the composer was working on Sonatas and Interludes,4′33″ became for Cage the epitome of his idea that any sounds constitute, or may constitute, music. It was also a reflection of the influence of Zen Buddhism, which Cage studied since the late 1940s. In a 1982 interview, and on numerous other occasions, Cage stated that 4′33″ was, in his opinion, his most important work.

John Milton Cage Jr. (September 5, 1912 – August 12, 1992) was an American composer, music theorist, writer, and artist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential American composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.

Cage is perhaps best known for his 1952 composition 4′33″, which is performed in the absence of deliberate sound; musicians who present the work do nothing aside from being present for the duration specified by the title. The content of the composition is not "four minutes and 33 seconds of silence," as is sometimes assumed, but rather the sounds of the environment heard by the audience during performance. The work's challenge to assumed definitions about musicianship and musical experience made it a popular and controversial topic both in musicology and the broader aesthetics of art and performance. Cage was also a pioneer of the prepared piano (a piano with its sound altered by objects placed between or on its strings or hammers), for which he wrote numerous dance-related works and a few concert pieces. The best known of these is Sonatas and Interludes (1946–48).

Carlos Kleiber (3 July 1930 – 13 July 2004) was a German-born, Austrian classical conductor who spent most of his early life in Berlin, Buenos Aires, Vienna and New York City, and from the early 1960s his professional career in Germany.

Kleiber was born as Karl Ludwig Kleiber in Berlin, the son of the Austrian conductor Erich Kleiber and American Ruth Goodrich, from California. In 1940, the Kleiber family emigrated to Buenos Aires. Karl's name became Carlos. As a youth, he had an English governess, grew up in English boarding schools. He also composed, sang, and played piano and timpani. While his father noticed his son's musical talents, Erich Kleiber nevertheless dissuaded Carlos from pursuing a musical career: "What a pity the boy is musically talented", wrote his father to a friend.^{[citation needed]}

Carlos Kleiber initially studied chemistry in Zürich, but soon decided to dedicate himself to music. He was repetiteur at the Gärtnerplatz Theatre in Munich in 1952, and made his conducting debut with the operetta Gasparone at Potsdam theatre in 1954. From 1958 to 1964 he was Kapellmeister at the Deutsche Oper am Rhein in Düsseldorf and Duisburg, and then at the Opera in Zürich from 1964 to 1966. Between 1966 and 1973 he was first Kapellmeister in Stuttgart, his last permanent post. During the following years, he often conducted at the Bavarian State Opera in Munich.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.

Grigory Lipmanovich Sokolov (Russian: Григо́рий Ли́пманович Соколо́в) is a concert pianist, often considered one of the greatest pianists alive. He was born April 18, 1950 in Saint Petersburg, Russia.

Sokolov began studying the piano at the age of five, entering the Leningrad Conservatory at age seven to study with Leah Zelikhman, later studying there with Moisey Khalfin. At age twelve he gave his first major recital in Moscow, in a concert of works by Bach, Beethoven, Schumann, Chopin, Mendelssohn, Rachmaninoff, Scriabin, Liszt, Debussy, and Shostakovich at the Philharmonic Society. At age sixteen he came to international attention when the jury at the 1966 International Tchaikovsky Piano Competition, headed by Emil Gilels, unanimously awarded him the Gold Medal. It seems this may have also been a surprising result: "16-year old Grisha Sokolov who finally became the winner of that competition was not taken seriously by anyone at that time."

"He possesses brilliant finger and chord technique, he easily wields the piano, so easily that he performs the prestissimo of the last movement of the Saint-Saens Concerto No. 2 with truly refined lightness. It was a startling performance. Doubtless we are going to hear much more about this young talented pianist..."
