"Gamma 4" is the fourth and final studio album by the band Gamma, released in 2000 through Ronnie Montrose’s independent label, RoMoCo. Coming years after the group’s earlier work in the late 1970s and early 1980s, the album marked a return for the project and served as a closing chapter in Gamma’s discography. It was later re-released in 2005 by Wounded Bird Records, helping reintroduce it to a wider audience. Notably, Gamma 4 is the last full-length album released during Ronnie Montrose’s lifetime to include his musical contributions, giving it particular historical and emotional significance within his career.
