Death metal song that starts off with classical piece

Thanks for all the replies.
Unfortunately its not Nile, that song kicks ass too.
Its also not Miasma or Golem.

I think "O Fortuna" is over-used and like any good piece of music,
because of its extensive use of playing it becomes dilluted.
Just like listening to a good song over and over, after a while it becomes
the gayest song ever.
But over all, I still believe it to be an awesome piece of work.
I didn't really like the Therion cover though.

Anyways, thanks again for all the replies, I'm still searching for the song
so if you have any ideas please reply, it'll really help out!
 
It sounds like TS described Nile's "Ramses Bringer of War", but I couldn't be sure unless I heard the piece he was talking about.
