Your statement above does not in any way support your position, though. While you may love heavy metal and think it REIGNS supreme, it is NOT the basis for all modern music and guitar playing techniques. I like it quite a bit, too, but don't be naive. As I said before, most of it was directly ripped from blues artists and altered. In fact, Iommi made the modifications to playing slower, louder, distorted and downtuned BECAUSE he couldn't play regular blues riffs due to two of his fingers being lopped off. Yes....Black Sabbath started off as a BLUES BAND, in which they were trying to emulate and copy their favorite blues artists but couldn't, so they changed their style and wound up creating something new. If it weren't for Howlin' Wolf, Tommy Iommi would have been a dishwasher.
