Which Herbie Hancock album includes the jazz-funk track "Chameleon"?

Herbie Hancock’s jazz-funk track “Chameleon” appears on the album Head Hunters. Released in 1973, Head Hunters marked a bold move by Hancock from acoustic jazz toward electric instruments, funk rhythms and studio experimentation.

“Chameleon” opens the album and is built around a famous bass-like synthesizer line played by Hancock on an ARP Odyssey. The composition was credited to Hancock, Bennie Maupin, Paul Jackson and Harvey Mason, who formed the core of the Head Hunters ensemble. Its long album version runs for roughly fifteen and a half minutes.

The piece’s groove is driven by a repeating two-chord vamp, leaving room for extended improvisation and solos. Hancock also plays Rhodes electric piano, while Maupin contributes on woodwinds. The track became one of the best-known jazz-funk instrumentals and later entered the repertoire of jazz, funk and fusion musicians.

The distractor albums are all Hancock titles, which makes this question easy to confuse. Man-Child, Thrust and Sextant are genuine albums from his electric period, but “Chameleon” is specifically associated with Head Hunters. The song’s standalone article is the clearest citation for the track itself.
