I'll have to admitt, the majority of shredders only shredd all the time. They cant do anything else and they think they are cool cause they can play really fast. But why do you think only a hand full of them recieve success when they shredd? Its becasue there are great shredders and there are the crap ones that you find making a mess of notes in a guitar shop like Led Zepplin or James stated. The reason why these people are great is because, even though they play fast, they pick the scales and progressions that evoke emotion in there songs. Led Zepplin, you want to know how someone playing really fast can be creative? Well this is why. When a slower great player plays, they are usually great for there ability to pick the most perfect notes so that they make what they are playing evoke feeling into the listener. The same goes for shredders. The great shredders can create a complex involvement of runs and sweeps and the end result can become quite breathtaking (about 3 I've heard can actually do it). You have to look at some of the 300+ note runs as a whole rather than individual notes played really fast one by one. But, I have to admitt something. Being in a room with the other 99% of other shredders is like being in hell.

thanks
