I recommend getting that one, Transylvanian Hunger, and Under a Funeral Moon, they truly embody black metal.
"today is the first time I've heard any Burzum"
It's cool, I've yet to hear anything from Darkthrone. I'll probably start off with A Blaze in the Northern Sky.
And i was listening to Isengard today(Fenriz's side project), it's awesome.
