Similar to the "Judgment Night" soundtrack, another Walters project which featured a fusion of hip hop music and rock music, the "Spawn" soundtrack consisted of collaborations between hard rock or heavy metal bands and electronic music acts. "Long Hard Road Out of Hell" features backing vocals from Kelli Ali, the front-woman of British trip hop band Sneaker Pimps. Neither Ali or her band-mate Liam Howe felt that the rock bands featured on the soundtrack were very good, but thought that collaborating with one of the bands would give them the chance to, in Howe's words, "polish a turd." Manson would recall that while recording the song, "The guitar player of the Sneaker Pimps had just got hit in the foreskin and he told me about it, which is a dumb as fuck thing to do, because the first thing I did was hit him in the dick, and I'm sure that probably added to the tension in the room."
