Black Metal.

People still talking about that (in documentaries or whatever) are still riding the wave of media hype and sensationalism because hipsters and 4channers discover Burzum and have to learn about all this crazy shit. There are much more relevant things going on nowadays, probably with much darker implications. But I digress.
 
Never really cared too much for the Greek sound. Current German and French scenes are great.

I probably wouldn't like the Greek scene as much but had a close friend from Greece show me alot of amazing artists, changed my opinion on the scene there. Love the stuff i hear now.

DODSFERD!

I mentioned a few pages back Abyssgale, check them out, think you'll enjoy them alot.
