Big Fun is a compilation album by American jazz musician Miles Davis.
It delivered at least two additions to the jazz-rock canon, both almost half an hour long: Wayne Shorter’s “Great Expectations”, performed by a mixed Indian and jazz ensemble composed of sitar, tabla, trumpet, guitar, piano, clarinet, saxophone, bass, drums and Airto Moreira on berimbau, and Davis' “Go Ahead John”, performed by a quintet (Davis, McLaughlin, Holland, DeJohnette, Steve Grossman on saxophone).
