Andrew Hill (born June 30, 1931 – April 20, 2007) was an American jazz pianist and composer. Hill first recorded as a sideman in 1955, but his reputation was made by his Blue Note recordings as leader from 1963 to 1969, which featured several other important post-bop musicians including Eric Dolphy, Bobby Hutcherson, Joe Henderson, Freddie Hubbard, Woody Shaw, and Tony Williams, as well as two of John Gilmore's rare outings away from Sun Ra.
