Shortly after his bandmates Clark and Gaddy died in 1969, Jarman joined Mitchell, Maghostut and Lester Bowie (trumpet) in the Roscoe Mitchell Art Ensemble in 1967; the group would be later rounded out with the addition of Don Moye on drums. This band eventually became known as the Art Ensemble of Chicago (AECO). The group was known for being costumed on stage for different reasons; Jarman wore facepaint and has mentioned that it "was sort of the shamanistic image coming from various cultures." The group moved to Paris in 1969 and lived there for many years in a commune that included Steve McCall, the great drummer who went on the form the jazz trio Air with Threadgill and bassist Fred Hopkins. Moving back to Chicago in the 1970s, Jarman lived in a musicians' building in Hyde Park, in Chicago, with Malachi Favors as his roommate. In 1983, he moved to Brooklyn, New York from Chicago and had lived there since that time.
