Black Metal.

Didn't Transilvanian Hunger also influence that part of black metal to a great extent? I'm not saying Burzum didn't but as far as "atmospheric" goes, that album sort of fits the bill. Especially for its time.
 
Another reason I brought up Transilvanian Hunger was Varg's involvement with it. So, perhaps he expanded further on ideas he had with that album.
 
He didn't. He wrote the lyrics for the final 4 tracks.

They were pretty bizarre as well. It's called TRANSILVANIAN HUNGER, Varg. I know you want to go back to that time and be the shrimpiest hipster viking who ever lived but for fuck's sake, at least get with the theme.
 
Speaking of Darkthrone, here's the cover art for their upcoming release Arctic Thunder. Supposedly it will be more serious and primitive compared to their recent efforts.

They probably mean it's a bit less sloppy and a bit more like their older stuff. Not that this is a bad thing, I like nearly every Darkthrone album.
