Philip Glass
Glass’ admitted artistic breakthrough came while working with Ravi Shankaron transcribing Indian music; the experience inspired him to begin structuring music by rhythmic phrases instead of by notation, forcing him to reject the 12-tone idiom of purist classical composition as well as traditional elements including harmony, melody, and tempo.
.. Glass’ growing fascination with non-Western musics inspired him to hitchhike across North Africa and India, finally returning to New York in 1967. There he began to develop his distinctively minimalist compositional style, his music consisting of hypnotically repetitious circular rhythms. While Glass quickly staked out territory in the blooming downtown art community, his work met with great resistance from the classical establishment, and to survive he was forced to work as a plumber and, later, as a cab driver.
