Born in Brooklyn, New York, Brian Damage played for Genocide and Verbal Abuse during his early musical career. In 1983, he was invited to join Misfits by the band's frontman Glenn Danzig. Damage was the latest in a long line of drummers that played for Misfits. The drummer's first performance, that took place in the Halloween gig of 1983, turned out to be the band's last show. Damage was thrown off the stage by the band's guitarist, Doyle, allegedly for being too drunk to keep up. Todd Swalla of the local band Necros filled the drummer spot for the rest of the show.
After his short period with Misfits, the drummer played for a number of New York City bands. He then moved to Los Angeles and played or recorded with Wink, Low Pop Suicide, Sylvain Sylvain, Susanna Hoffs, and The Fuzztones, among others. He also did live performances with African Violet, Jason Falkner, Woozy, and Dave Vanian and the Phantom Chords; and recorded sessions demos with Bijou Phillips, Swirl 360 (with Roger Manning), Tallulah, Kim Richey, Marie Wilson, Billy Idol, Tom Anderson, Leah Andreone, and Colony.
