The band claim that they are a black metal and dark ambient band which, judging from the intro and outro, could be true. Both are indeed very dark and fearsome soundscapes which are perfectly suited to open and close this otherwise fierce and brutal album. I always like these passages and I no longer see them as mere intros or fillers. These are an important part of an album, if done right.
What follows is raw, harsh, bleak and eerie black metal, reminding me of acts like Burzum, Darkthrone and many other old school black metal bands. Here and there I think I can hear some keyboards but at this volume I'm not sure if they are there or just in my head. The album really takes me back to the days where the genre had a certain psychotic insanity. Here, that madness is represented by the fearsome vocals.
Besides, there are some awesome tracks here. 'Spiritueller Selbstmord', for example, is a (mainly) slow but stunningly crushing piece of work which could be a classic in its genre. It's followed by the intense thrasher 'Negativität', another massive blast of extreme metal with a thick wall-of-sound attitude. The energy coming from that song is incredible. I guess this one is my favorite.
So yes, I do urge you to check out this gem if you're a black metal fan, regardless of which era. This is as vintage as it gets these days. This is old school black metal from a very high level and with a very solid nineties feel. But most of all, of course, this is sick!!!
