In addition to the Dirtbombs, Collins has played in the Screws, an eclectic punk band that has released two albums since 1999 and has appeared on several compilations.

He also played music with the Voltaire Brothers, a funk project that issued a 2002 album, I Sing The Booty Electric.

The first edition premiered on June 3, 2006, and included musical journeys of Motown soul legends Junior Walker & The All-Stars, Jazz artist Joe Williams, 1950s rock 'n roll star Fats Domino, and 1980s Detroit garage band The Hysteric Narcotics.
