nice to see someone else around here recognizes him for what he is!
Edit: however, for a lesson, you must include his spider chord technique. look it up.
Oh he's my all time favorite guitarist! The reason I started to love metal was when I first heard Symphony of Destruction. Then I got the greatest hits CD and WOW. Blown away. The spider riff isn't really too hard, it's just cool as hell! lol. I use it in my song Carnivale at the final speed run. Here's the tab you can probably see where I use it. It helps me keep up the speed and not have to focus on reaching that power chord on the 6th fret. Long live Mustaine! lol
