Black metal forefathers, or should I say “forekids” supposedly made their low quality music as a rebellion against the Morrisound production of some death metal bands, but their “rebellion” created conformity, not something unique, and it was an adherence to gayness. I don’t think that their sub par music would have become popular without the silly crimes. I proved that when I made a demo of “Svarog” and it sold out of two pressings immediately. 
Even if Deicide and Suffocation went to Morrissound – they had completely different styles. But let’s give the gaylords of chaos that concession – let’s pretend that all bands that went to Morrissound were the exact same style, death metal was underground music, so it was the black metallers who were posers because they only listened to the popular death metal albums. Far more brutal music was created by bands like INIQUITY from Denmark, back then on DIE HARD RECORDS, and other such terrifying and phenomenally skillful bands were quite plentiful, if you didn’t get your metal shopping done by your mommy, or reading mainstream mags. Fuck black metal. (INIQUITY made a perfect album called “Seranadium” – it is your duty to buy this)
