Venom were the first truly important band when it came to extreme metal - the Quietus writes in a great article about how Venom got together and started what is now known as black metal. Band's frontman Cronos explains: “I love the idea of extreme metal. I just think you can't go too far... so long as it's just within the music y'know. The further the better, the more extreme the better, the more notorious, the more hardcore”. Band's 'Sons Of Satan: Rare & unreleased demos 79-84' is out now.
