"Andrew Charles Cyrille (born November 10, 1939) 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.

Cyrille was born on November 10, 1939, in Brooklyn, New York into a Haitian family. He began studying science at St. John's University, but was already playing jazz in the evenings and switched his studies to the Juilliard School. His first drum teachers were fellow Brooklyn-based drummers Willie Jones and Lenny McBrowne; through them, Cyrille met Max Roach. Nonetheless, Cyrille became a disciple of Philly Joe Jones, who in some performances such as Time Waits used Cyrille's drum kit.

His first professional engagement was as an accompanist of singer Nellie Lutcher, and he had an early recording session with Coleman Hawkins. Trumpeter Ted Curson introduced him to pianist Cecil Taylor when Cyrille was 18.

He joined the Cecil Taylor unit in 1964, and stayed for about 10 years, eventually performing drum duos with Milford Graves. In addition to recording as a bandleader, he has recorded and/or performed with musicians such as David Murray, Irène Schweizer, Marilyn Crispell, Carla Bley, Butch Morris and Reggie Workman among others. Cyrille is currently a member of the group, Trio 3, with Oliver Lake and Reggie Workman."
