For me, I've never really gotten into Black Metal too much. But I do LOVE early Venom - the masters of Black Metal. I'm a massive fan of their work on the first few albums, especially stuff like
Buried Alive,
Countess Bathory and this awesome track...

There's something so fascinating about the genre though - I'm not sure what it is. Like something is drawing me to it whenever I hear it/read about it. There was this great article in Metal Hammer a couple of years back about Norwegian Black Metal and I just couldn't stop reading it.
