Never got too far into black metal, but it's always worth checking out Burzum, Immortal, Mayhem, and Wolves in the throne room. Blackened death on the other hand is some of my favorite music to listen too. Start with those guys and it should be pretty easy to branch out in a few different ways with them.
I will lay down my bones among the rocks and roots of the deepest hollow next to the streambed
The quiet hum of the earth's dreaming is my new song
