What is the music from the trailer of Beowulf?Music

[Venari]

I've heard it recently, on another film. I have too many films to figure which it is, so what the heck is the original piece, and who is it by?

Not to be totally off topic or anything but there is going to be a Beowulf movie? I love the poem. Where may I view this trailer?
