Without a doubt, Michael Angelo Batio is one of the best technically advanced guitarists there has ever been, and probably ever will be.
The following is a video lesson taken from a DVD called Speed Kills where Batio teaches you picking techniques for speed and shredding. Highly recommended!
Shown in this excerpt are some alternate picking exercises. Alternate picking is a technique that must be learned in order to play fast and to shred. Why not learn from one of the fastest there ever was?
