Till a week ago I had never listened to black metal.
Then the lovely Lamb Of God sent me some you tube links and now I am loving it.
So far I am loving IMMORTAL, DIMMU BORGIR, MARDUK, GORGOROTH.
My favorite Black Metal band is Goatpennis (BBM) , a band from Santa Catarina, Brazil.
If it doesn't fit in the question, my favorite band i Mystifier, also from Brazil.
