Collage is a compilation album by American glam metal band Ratt. It consists of alternate recordings, B-sides, and versions of songs from the band's Mickey Ratt period. It was mostly recorded and released in 1997, concurrently with Ratt's reunion tour, so that they would have a new album to promote. In 1998, the band would sign a new major label deal with Sony.
The track "Mother Blues" first appeared as an Arcade song on their 1993 self-titled release, but was originally a Ratt demo, ending up on Collage. "Steel River" is an alternate version of the Mickey Ratt song "Railbreak".
