Ronald Shannon Jackson (January 12, 1940 – October 19, 2013) was an American jazz drummer from Fort Worth, Texas. A pioneer of avant-garde jazz, free funk, and jazz fusion, he appeared on over 50 albums as a bandleader, sideman, arranger, and producer. Jackson and bassist Sirone are the only musicians to have performed and recorded with the three prime shapers of free jazz: pianist Cecil Taylor, and saxophonists Ornette Coleman and Albert Ayler.
