Kronos Quarted were involved in the soundtrack to "Requiem for a Dream"
Easily the most disturbing movie ever made, and thier work did an amazing job of setting the mood and atmosphere of the movie. In fact, i think the music is one of the apects that made the movie so stunning, and it deinatly leaves a lasting imprint on your mind.
If you get a chance, pick up the soundtrack for this movie, awesome music, it just grabs a hold of you and wont let go. Kinda like the movie. I really dont normally go for soundtracks, but this one i can just sit and listen to.
Better yet, get the movie too, and dont be suprised when it stays in your head weeks after you see it.
