That was average new metal riffing, in dropped D tuning, nonethelss. nothing fancy. He was nice and tight, though.... many players haven't learned how to NOT play, meaning, they haven't learned that the space between notes needs to be clean.
I saw that last link (Canon in D) and that guy's pretty slick. It's a bit more my style of playing.
I was influenced by megadeth, Extreme, Testament and Metallica. I could play the entire Justice For All album note for note when I was 17. (solos and all) All it takes is massive dedication to your instrument, to get good..... and alot of time. I've been playing guitar for 16 years and the past 5 years I've been doing it proffessionally.
