“Supernaut” was originally written and recorded by Black Sabbath on their 1972 album Vol. 4. In 1990, Al Jourgenson’s side project 1000 Homo DJs recorded an industrial rock cover of it.

The official release credits Al Jourgensen (as Buck Satan) on vocals, but the song was originally recorded with Trent Reznor on vocals. Reznor once explained:

The version of “Supernaut” that eventually came out is not me singing. The one that we originally did had me singing the lead, but because my record label in America TVT, which is the shittiest label in the entire planet, totally shit their pants about it and made a big hassle about it [it couldn’t be released]. Basically, it was me and Al (Jourgenson) hanging out in a studio together, totally drunk. So after 2 months of my label fighting with Waxtrax I called him up and said, “Redo it, save yourself the hassle.”

Officially, Reznor’s vocals appear on the original Wax Trax! cassette sampler, and then were replaced by Jourgensen’s vocals for the EP release and for the song’s inclusion on the 1994 Nativity In Black compilation, with the Reznor vocals restored for the 1994 Wax Trax! Black Box compilation. The close similarity between these two versions has led to longstanding speculation that those versions credited to Jourgensen are the original take run through a slightly fuzzier distortion.
