Having taken a shot at Black Metal I felt it was only fair to let "the other guy" have his chance, so here's some Christian metal for ya. Um, Christian Death Metal?
Primitive rhythm machine --- Mortification --- 1995
I must admit, the only real CM I know is the likes of Theocracy, Narnia and of course Stryper, so this could be a revelation (hah!), though to be honest the name of the band sounds more like something you'd expect from a straight-up death or black metal band. Nevertheless, they have over 20 albums and to add to the strangeness they're Australian!
Well, the vocal is death metal but I can kind of make it out. I guess without the vocals/lyric there's no way to tell that this is in any way Christian metal. Meh. Not that great though.
Mind you, you'd think their lyrical themes would be a little limited wouldn't you? Puts me in mind of this from the Simpsons (although whoever thought Priest were death metal must have been on something really strong...)
