Nokturnal Mortum is awesome. I love Weltanschauung and Goat Horns, the other albums are great too but I haven't listened to them as much. I think Return of the Vampire Lord is one of my favorite tracks from them though that EP was just OK overall to me. I also really love Perun's Celestial Silver, which is on NeChrist, but don't remember some of the tracks on there. Haven't listened to it in awhile.
Bah, there's nothing inherently wrong with liking music that contains racist lyrics tbh. Don't have to agree with the message to like the art. It's funny a friend posted something to the affect of "I see you liking racist record labels!" it's like is nobody allowed to employ a racist? I suppose they are suppose to be homeless and starve to death or something.
