Gamma 2 is Gamma's second album, released in 1980. On this album Ronnie Montrose keeps his streak of not having the same personnel on two albums in a row, changing the line-up once again. Davey Pattison (vocals), Montrose (guitar), and Jim Alcivar (synthesizer) remain from Gamma 1. Glenn Letsch replaces Alan Fitzgerald on bass and old Montrose bandmate Denny Carmassi replaces Skip Gillette on drums.

Cover

The cover image was photographed by Jeffrey Scales to a design by Mick Haggerty. The original image had a lone woman on the sunbed but a man was added after record executives raised concerns over the appearance of sharks attacking vulnerable woman. Mick Haggerty felt the change improved the image.
