I was just watching him play on youtube as well. There are quite a few performances by him. I listened to some clips from his cd's as well and he does have a great style. I like the sound and the fact that it all comes from one guitar. Very impressive.
Up to a year or so back Andy was giving guitar lessons at the local Fender dealer in my old hometown. While his style is not my cup of tea, there is no doubt that the guy is loaded with talent and is finally getting some well deserved recognition.
