William Parker (born January 10, 1952) is an American free jazz double bassist, multi-instrumentalist, poet and composer.
Parker was born Bronx, New York City. He was not formally trained as a classical player, though he did study with Jimmy Garrison, Richard Davis, and Wilbur Ware and learned the tradition. Parker is one of few jazz bassists who regularly plays arco. He also plays several other instruments from around the world, including the West African kora.
While Parker has been active since the early 1970s; he has had a higher public profile since the early 1990s. He is a prominent and influential musician in the New York City experimental jazz scene, and has regularly appeared at music festivals around the world, including the Guelph Jazz Festival, in southern Ontario.
Parker first came to public attention with pianist Cecil Taylor. He has long been a member of saxophonist David S. Ware's quartet and in Peter Brötzmann' s groups.
He is a member of the cooperative Other Dimensions In Music. Together with his wife organizes the annual Vision Festival in New York City.
