Personally I think that no list of geniuses is complete without Venom's Mantas on the number one spot.................that guy invented music, without being able to tune his guitar. His incredible solo on "Witching hour" is still one of the finest moments in recorded musical history. Saw him once in concert and I was nearly deaf for a week............the effect is shattering.
Without Mantas there would never have been players like Blackmore, Rhoads, Van Halen or Blind Melon Chitlin, so with all respect, I only discuss music with people who believe in true music: Black Metal!!!
