"Chameleon" is a jazz fusion standard composed by Herbie Hancock with Bennie Maupin, Paul Jackson and Harvey Mason,[3] all of whom also performed the original 15:44 full-length version on the 1973 album Head Hunters,[4] and featuring solos by Hancock and Maupin. The 9:41 edit omits an out-of-tune segment, features a new bassline added in at around 6:40 and new instruments added in post-production.
