Side Trax is a compilation album from industrial metal band Ministry. The album was released in October 2004. It compiles EPs from four Ministry side projects recorded in the late 1980s: Pailhead, 1000 Homo DJs, PTP, and Acid Horse. All of the songs were originally released on Wax Trax! Records, with the exception of PTP's previously-unreleased "Show Me Your Spine." Notably, the rare version of 1000 Homo DJs' "Supernaut" with Trent Reznor of Nine Inch Nails on vocals is included on this compilation.
