Former Redd Kross and Air drummer and composer Brian Reitzell has already scored "Lost in Translation" and "The Virgin Suicides", but this is his first horror feature film. I just went to see the today and was able to enjoy the soundtrack in its full grandness over the sound system of the theater. Obviously the impact that it has at that loudness and coupled with moving images is by far greater than that just a CD could have, but nevertheless, the CD stands on its own as a good release, and Mike Patton's label Ipecac saw that and decided to put it out. Musically you can think of it as a Cold Meat Industry type of release: glacial and minimal with random or sporadic bursts of brutal and sheer sonic attacks, isolationistic dark ambient with pounding industrial mayhems... the palette of moods and colors that is drawn is pretty non-sequential and is not based on a recurring harmonic theme (as in most other movies); in fact the entire soundtrack mostly consists of sounds that in the theater likely blend in with the sound design and don't take on a song-dimension of their own. In other words it is perfect for a movie about a bunch of people stuck in the dark at ten below zero with blood thirsty vampires hunting them down!
Rietzell's approach was quite unique and unheard of: he created his sounds by affixing various instruments and objects to a pottery wheel with microphones that was spinning at up to 280rpm... I really wish I was there to see that.
Rietzell is currently working with members of Air and Spoon on the soundtrack for a movie that doesn't yet exist, so whenever he figures that one out (or he gets an offer by some director working on a similar concept) we might hear more of him.
