He worked with playwright Ntozake Shange, poet Jessica Hagedorn, and poet Thulani Davis at the Public Theatre, New York City. Following this he began working more in rock, jazz fusion, and R&B. He worked with Walter Becker of Steely Dan. In 1983 Nile Rodgers produced Situation-X for Island Records.

In 2013 he formed Michael Gregory Jackson's Clarity Quartet and Michael Gregory Jackson's Clarity TRiO.

"Jerome Douglas Cooper (December 14, 1946 - May 6, 2015) was an American free jazz musician. In addition to trap drums, Cooper played balafon, chirimia and various electronic instruments, and referred to himself as a "multi-dimensional drummer," meaning that his playing involved "layers of sounds and rhythms". AllMusic reviewer Ron Wynn called him "A sparkling drummer and percussionist... An excellent accompanist". Another Allmusic reviewer stated that "in the truest sense this drummer is a magician, adept at transformation and the creation of sacred space".

Cooper studied with Oliver Coleman and Walter Dyett in the late 1950s and early 1960s, then studied at the American Conservatory of Music and Loop College. In 1968, he worked with Oscar Brown, Jr. and Kalaparusha Maurice McIntyre in the U.S. but moved to Europe before the end of the decade, where he played with Rahsaan Roland Kirk, Steve Lacy, Lou Bennett (with whom he visited Gambia and Senegal), the Art Ensemble of Chicago, Alan Silva, and Noah Howard. After returning to the U.S. in 1971, he joined the Revolutionary Ensemble alongside Leroy Jenkins and Sirone, where he remained for several years, and played piano, flute, and bugle in addition to drums. In the 1970s, he played with Sam Rivers, George Adams, Karl Berger, Andrew Hill, and Anthony Braxton. In the 1980s he worked with McIntyre again, as well as with Cecil Taylor.

Cooper died in Brooklyn on May 6, 2015, aged 68, from complications of multiple myeloma, according to his daughter, Levanah Cummins-Cooper."
