Rhys Chatham began his musical career as a piano tuner for avant-garde pioneer La Monte Young as well as harpsichord tuner for Gustav Leonhardt, Rosalyn Tureck and Glenn Gould.
He soon studied under electronic music pioneer Morton Subotnick and minimalist icon La Monte Young and was a member of Young's group, The Theater of Eternal Music, during the early seventies; Chatham also played with Tony Conrad
in an early version of Conrad's group, The Dream Syndicate. In 1971, while still in his teens, Chatham became the first music director at the experimental art space The Kitchen in lower Manhattan. His early works, such as Two Gongs (1971) owed a significant debt to Young and other minimalists.His concert productions included experimenters Maryanne Amacher, Robert Ashley, Philip Glass, Meredith Monk, Pauline Oliveros
, Steve Reich, and early alternative rockers such as Fred Frith, Robert Fripp, Arto Lindsay, and John Lurie. He has worked closely with visual artist/musician Robert Longo, particularly in the 1980s, and on an experimental opera called XS: The Opera Opus (1984-6) with the visual artist Joseph Nechvatal.
By 1977, Chatham's music was heavily influenced by punk rock, having seen an early Ramones concert. He was particularly intrigued by and influential upon the group of artists music critics would label No Wave in 1978. Members of the New York City noise rock band Band of Susans began their careers in Chatham's ensembles; they later performed a cover of Chatham's "Guitar Trio" on their 1991 album, The Word And The Flesh. (This parallels the way that members of fellow NYC noise rockers Sonic Youth began their careers in Branca's ensembles; Thurston Moore of Sonic Youth
did play with Chatham as well.)
Chatham began playing trumpet in 1983, and his more recent works explore improvisatory trumpet solos; these are performed by Chatham himself, employing much of the same amplification and effects that he acquired with the guitar, over synthesized dance rhythms by the composer Martin Wheeler.
