Fair enough, but IMO Sabbath would kack their pants if they'd attempt anything as evil-sounding as Crimso at their darkest (Fracture from 'Starless and Bible Black" for example)... not to mention the fact that they couldn't play that, even if they wishedJohnny_Peebucks wrote:King Crimson "Slow, grinding riffs, heavily distorted guitar, anguished and doomy lyrics" - Nah, just weak, hippie crap with some free form Jazz at the end,that's why I would put Sabbath over that...but that's just me.

Btw did you know that the "hippie crap" above (21st Centruty Schizoid Man) was lovingly covered by the Swedish death metallers Entombed on their Family Favourites EP? Only even they could not negotiate their way through the fast unisono part after the 'jazzy' middle section. Go figure. But it's interesting to know some history beyond the cave-man riffs.
Speaking of which... Bartók and Stravinsky dabbled with the kind of atonal, chugging and angular riffing, tritones and all, that characterize 'modern heavy metal'... almost a century ago... although obviously they did not have electric guitars. You can't find many examples on youtube (thank god!) but here's just some to whet the appetite. Or not, but anyway
