Explosions in the Sky is probably one of the most underrated experimental/mood rock groups out there and good lord, am I all up their ass right now. After seeing the movie (fantastic by the way), I found it hard not to notice how extremely beautiful the background music was. Very airy and mood inspiring and it pretty much made the movie. Anyhoo, please check them out if you wish.

I would have to say that they are a perfect group to listen to while doing anything. Just great music to work to. No lyrics, just great instrument playing. Quiet at times and then explosive (pardon the pun).
