I say DiMeola and Holdsworth because those were the first two concerts I went to, they totally changed how I looked at the electric guitar. Even when i was really young I just didn't find pop players like eddie van halen, kirk hammet, randy rhoades very interesting.
As for my style, I've been studying classical guitar for a while, when i started playing electric I only played in that Gambale/Garsed style, but ever since I heard the faster players like Paul Gilbert I spend more time shredding.
