Need ANY help with this song question, please!!?

Okay, this is a random song question. On the movie The Descent (2006)...it's the movie with the girls that go down into the cave, get trapped, have to fend off against the monsters, etc...well, when you buy the DVD and watch the bloopers, a very awesome song plays. Does anybody know the song and/or artist? Would love to know, thanks!! Please help!
