Andrew Charles Cyrille is an American avant-garde jazz drummer. Throughout his career, he has performed both as a leader and a sideman in the bands of Walt Dickerson and Cecil Taylor, among others. AllMusic biographer Chris Kelsey wrote: "Few free-jazz drummers play with a tenth of Cyrille's grace and authority. His energy is unflagging, his power absolute, tempered only by an ever-present sense of propriety."
