Amazing music.
Simply AMAZING.
I just got both their albums and have been listening to them nonstop.

You've most likely heard their tracks in movies, or movie trailers without knowing it.

For example.. if you haven't heard this somewhere, I'd be surprised.

+ YouTube Video

I've heard this name before, and the song sounds familiar as well. Good stuff! I'll check them out!

First heard about them when I played Plasma Pong. :P

They are the definition of EPIC.

I need to get their second album though.

They certainly sound different, and i'm a different type of guy so this appeals to me. I quite enjoy when music twists in to each oter, e.g. turisas-Battle/viking metal. Children Of Bodom-Neo classical. and skindred-rap/reggae/metal/punk/hip-hop. It does sound like some sort oif hitman theme tune though as you said. The rock vs classical theme is good. It is a good clash.
