Ron "Bumblefoot" Thal, who you might know from Guns N' Roses and Art Of Anarchy, is one hell of a guitarist. Dude can also sing extremely well too, which is why watching him rip out classics from Iron Maiden, Judas Priest, Black Sabbath, Dio, and a few others on a Hello Kitty guitar is pretty awesome. The whole video is great, though I was most impressed with the high notes on "Queen Of The Reich."
No word on how Zakk Wylde feels about the guitar cheating on him.
