Also, Troy Stetina's "Speed Mechanics for Lead Guitar" is near-mythical for a good reason - not so much on theory or musicality, per se, but if you want the best physiological analysis of the mechanical process involved in playing guitar, and ways to minimize resistance to build speed and finger independance, this is it.
In terms of books, I'd recommend one called 'The Complete Guitarist' by Richard Chapman. This book covers absolutely everything. I've had my copy for about 7 years, and I still refer to it every so often. Any of Paul Gilbert's videos are great for general technique as well.
Im now thinking about ordering: Speed Mechanics Rock Discipline George Lynch's Reh vid OR Intense rock I
I may order them in the next couple of days. A few of questions though... 1. Which is better out of George Lynch's Reh vid and Intense rock I ?? 2. I know this may sound stupid but can anyone get me a link to intense rock on licklibrary?? 3. What is a good vid for sweep picking??
