I love August's riffing, it reminds me of Aspera Hiems Symphonia.
The drumming is spectacular as you would expect from Hellhammer, he is one of the few amazing drummers of all time I think. The viola violin and chello give it a more traditional folk/classical sound which blend together nicely. And the words are delivered pretty well, yet I think a few of the line's could have been screamed to end some of the breaks. It seems the way it was done you can play it around more timid company without pissing them off and starting a Debate. 1 to 10 I'd say 9.9. Of course I must add there are many 9.9 releases this one works for me. The extra .1 to get a 10 stays there as to not upset the gods.
