Gamma was an American hard rock band formed by guitarist Ronnie Montrose and singer Davey Pattison in San Francisco in 1979.

The original lineup of Ronnie Montrose (guitars), Davey Pattison (vocals), Alan Fitzgerald (bass), Jim Alcivar (keyboards) and Skip Gillette (drums) recorded this album.

Alan Fitzgerald (who later joined Night Ranger as their keyboardist) was replaced by bassist Glenn Letsch, and Denny Carmassi (another ex-Montrose member) came in on drums.

The new line-up was Davey Pattison (vocals), Ronnie Montrose (guitar), Denny Carmassi (drums), Glenn Letsch (bass), and Ed Roth (keyboards).

They started with Gamma 2 which includes 24 bit remastering from original source tapes and extensive liner notes with comments from Glenn Letsch.

After the death of Ronnie Montrose on March 3, 2012, the original members of Gamma (plus Marc Bonilla on guitar) performed to a sell out memorial concert in San Francisco, California.

Gamma was reformed with Pattison on vocals, Dan Buch (Butch) on drums, Van Spragins on bass, Tommy Merry on guitar and Brad Barth on keyboards.
