Who would've thought that a thread from 4 years ago would suddenly gear out and cause such an argument... over slipknot at that. I'll credit them as being capable musicians, but for as much talk as they've done I think they've failed at living up to their words. If you really feel like taking my view and firing off a thread in retaliation to defend the slipknot name then go ahead. As for Joe Petrucci, maybe he's a hybrid between Jon Petrucci and Joe Satriani creating a super guitarist.
