That guy your talking about from Nitro jack7 is the guitarist called Michael Angelo. He's ambidextrouse (I'm a horrible speller) and can play guitar with either hand equally. The whole point of that band was to put together the fastest guitar ever recorded (Micheal surpassed it on his solo work) and the wildest vocals of Jim Gellette (again i think i spelled his name wrong but I'm sure a few of you know what I'm talking about).
