Black Metal.

Black Metal is pretty controversial to the public; especially after the frontman for Burzum burned a few churches and killed someone. But personally, I love black metal, especially Dark Funeral, Celtic Frost and Mayhem.

Celtic Frost are the gods of black metal imo.
 
Verdunkeln is a Burzum ripoff, quite enjoyable, recommended, if you don't feel like relistening Hvis Lyset Tar Oss, in my opinion a lot better than The Ruins of Beverast which is unbearably boring and uses those crapy samples, which I so much dislike. I especially liked the second album "blick in den qualenfal" or something like that, sorry if it's inexact I'm typing it from memory.
But the real question for today is what do you think of Beherit's Engram. Personally I think it's quite bad. Simple and raw, below Beherit's standards with a clear production that totally demystifies the music. The riffs are old Beherit riffs recycled, with some Celtic Frost touches on the last track. It's just irrelevant for today but it wouldn't have been much even 20 years ago.
