Chameleon is a 1972 album by the Four Seasons, notable for being their only album with Motown and the only one featuring Demetri Callas on guitar; Callas had replaced band co-founder Tommy DeVito in 1970 but left in 1974, replaced by Don Ciccone and John Paiva during the band's mid-1970s renaissance.

Some, however, later turned up on Frankie Valli's 1975 "solo" album Inside You, which was a collection of unreleased songs and outtakes from Chameleon.

[7] Chameleon was unavailable on compact disc until 2008, when Universal Music Group, the parent owner of Motown Records, released a 2-disc compilation titled Frankie Valli and the Four Seasons: The Motown Years.

With this release, all of the Four Seasons' material recorded for Motown is now accessible to a new audience, as well as for longtime fans.
