Chatham began his musical career as a piano tuner for avant-garde pioneer La Monte Young as well as harpsichord tuner for Gustav Leonhard, Rosalyn Turek and Glenn Gould. He soon studied under electronic music pioneer Morton Subotnick and minimalist icon Tony Conrad; Chatham and Conrad played together in an early ensemble. 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 Brian Eno, Robert Fripp, John Lurie, and Fred Frith. 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.

Compositions from the late 1970s and early 1980s
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. That year, he began performing Guitar Trio around downtown Manhattan with an ensemble that included Glenn Branca, as well as Nina Canal of Ut. During this period, he wrote several works for large guitar ensembles, including Drastic Classicism, a collaboration with dancer Karole Armitage. Drastic Classicism was first released in 1982 on the compilation New Music from Antarctica, put together by Kit Fitzgerald, John Sanborn and Peter Laurence Gordon. It was also included on the 1987 album that also included his 1982 composition Die Donnergötter (German for "The Thundergods").

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. His 1990s recordings in this style saw release on Ninja Tune Records as the compilation Neon.
