Can't say it's my favorite genre, but it's certainly up there. Love old style thrash/black (Venom, Hellhammer/C Frost/Decayed...) and squizo BM like early-Filii Nigrantium Infernalium. Not so much into Norwegian BM, find it kind of repetitive, but I like classic Mayhem.
In fact, I remember you sent me some Arrow postcards and I wanted to send somethimng related to BM back to you, but you didn't give me your address
