Finally someone posts a solid metal song that is purely instrumental, and not distorted by vocals. As a life-long fan of Black Metal, I love and hate the genre. I love the violent instrumentals, and I can easily live with the devil worshipping and mythological lyrics. However, why does the singer always have to sound either like a cat being castrated, or the cookie monster stuck on the -kie syllable?
I guess I have to back that up with an instrumental recommendation on my own. I would like to heavily suggest playing Metal: Hellsinger if you want a game with good music. It is basically a rhythmical first person shooter, and really fun.
