Carla Bley (born Lovella May Borg; May 11, 1936 – October 17, 2023) was an American jazz composer, pianist, organist, and bandleader. An important figure in the free jazz movement of the 1960s, she was perhaps best known for her jazz opera Escalator over the Hill (released as a triple LP set), as well as a book of compositions that have been performed by many other artists, including Gary Burton, Jimmy Giuffre, George Russell, Art Farmer, Robert Wyatt, John Scofield, and her ex-husband Paul Bley. She was a pioneer in the development of independent artist-owned record labels, and recorded over two dozen albums between 1966 and 2019.
