Roscoe Mitchell (b. August 3, 1940 in Chicago, Illinois) is an African American composer, jazz
instrumentalist and educator, mostly known for being "a technically superb—if idiosyncrati —saxophonist." He has been called one of the key figures in avant-garde jazz who has been at the forefront of modern music for the past thirty years. He continues to be a major figure. He has even been called a super musician and the New York Times has mentioned that he qualifies as an iconoclast.
In 1965, Mitchell was one of the first members of the non-profit organization Association for the Advancement of Creative Musicians (AACM) along with Phil Cohran . The following year Mitchell began what would later become known as the Art Ensemble Of Chicago.
