I have to post on this, because if I don't I feel I will be doing the rest of you a disservice.
E Nomine is one of the most amazing musical groups ever. I would define their style as "choir driven industrial trance" (I thought that one up myself!

). Classic psalms and latin pieces are put to industrial trance in a way that gives me shivers, it's so good. ErMaC's Lord's Prayer X video was done to one of their songs, Vater Unser. My favorite song is Mitternacht (extended version). It inspires me to make videos, videos, videos, yet I don't have a way to get clips for anything that would work. I found their stuff on Kazaa, and I'm trying to see if I can order a CD anywhere.
