Live-Evil is an album of both live and studio recordings by the American jazz musician Miles Davis. Parts of the album featured music from Davis' concert at the Cellar Door in 1970, which producer Teo Macero subsequently edited and pieced together in the studio. They were performed as lengthy, dense jams in the jazz-rock style, while the studio recordings consisted mostly of renditions of Hermeto Pascoal compositions. The album was originally released on November 17, 1971.

Jazz fusion is a popular music genre that developed in the late 1960s when musicians combined jazz harmony and improvisation with rock music, funk, and rhythm and blues. Electric guitars, amplifiers, and keyboards that were popular in rock and roll started to be used by jazz musicians, particularly those who had grown up listening to rock and roll.
