First Black Metal Band

D) I realise point A), I was merely giving my own opinion
E) re B): Shut up
F) see E)

The weird thing about Countess is, a lot of their stuff is in Dutch. And as a Dutchie myself I find it a little strange looking. But I'd like to check it out to see if it's worth listening to. I guess the fact that it's Dutch doesn't matter too much whent he lyrics are presumably unintelligable for the most part.
 
The best to start with is probably Heilig Vuur, but it's not the best. Just don't start with The Gospel Of The Horned One or The Shining Swords Of Hate.
 
Bathory as far as my opinion counts
Venom was the first to coin the term
Mayhem would probably be the first to play Black Metal close to what its known as today
