I recommend starting with at least 4 hours of Kerry KingLive onVHS/DVD,cuz he is real easy to study/emulate.I'll say he's original,and does'nt think about the rules.In their big "hit" Seasons in The Abyss" is a great example.1st Half of the solo is clearly rooted in F,,andKing goes and plays a 2 octave run in F# Aeolian?!?!?! That blew my mind,and it came at a time in my playing,when i worried about maybe hitting a C instead of C#,but with Kerry,rules??? thre are no rules.Balls and A Big Whammy!!!!!
