I was curious as to if he has done any original/cover songs for sountracks or for other artists that are not featured on the Halos.
I want to say that Trent did the soundtrack for Quake.
The Crow: Dead Souls (Joy Division cover)
Natural Born Killers: Burn (original)
Lost Highway: The Perfect Drug (original)
The Soundtrack for the first Quake
He was also a member of 1,000 Homo DJs, where he did the lead vocals on a cover of Black Sabbath’s “Supernaut”. His record label at the time, TVT, flipped out and demanded that his performances be removed, so parts of the track were overdubbed by Al Jourgensen. Some of the original performance does remain. I believe Trent also had some involvement in the other two tracks on that single, as well.
IIRC, Trent produced Bowie’s “I’m Afraid of Americans,” and you can definitely tell. But I don’t have the album. Anyone know if Trent played on the single?
http://9inchnails.com/discography/index.php has everything he’s ever done, as far as I can tell. Of particular interest to you will be the Miscellaneous and Soundtracks sections.
I should mention that he also was working on the soundtrack for Doom 3, but apparently dropped out because the game was taking too long to complete.
