Mexican Guitarristas Rule

A few months ago I saw Roderigo y Gabriela on the Lopez show and they rocked the house. Gabriela's rhythm guitar work is even more jaw-dropping in this clip, especially around 1:20 in. The fact that a technique has a name (like triplets) doesn't mean it's not impossible. Personally, I think playing with your knuckles is cheating, as is knowing more than 3 chords.
