I place Dimebag Darrell in that category. A lot of metalheads don't realize how insanely talented he was. I wasn't fortunate enough to see him live, but my friend saw him on tour in Brazil and told me some stories about how Dime came out chugging straight Crown, handed off his liquor cup to some fans, and then proceeded to play every son, every solo note for note. And keep in mind, Pantera js a one guitar band, there is no backing guitar to hide any mistakes. And he had such raw, unbridled energy and power he didn't need any backing.
