I know a small hand full of you guys enjoy some of the videos I post and I think this one you guys will like. This is probably THE best guitar quartet around. All of them are accomplished guitarists on their own (famous in fact) and having them play together is like having SRV, Clapton, BB king and Hendrix all playing together (not exactly, but you get the idea).
Heres my favourate:
Type in "LAGQ" in youtube, they have a lot of videos.
