I'm amping to learn how to do percussive guitar playing - something like Rodrigo y Gabriela do: mostly Gabriela's playing actually. I know different people like to do their beats differently and so on and so forth; there are many ways to do the same or similar things - I've noticed that on YouTube flicking through a couple videos. Does anyone know of any good (and free) lessons floating around on the internet? I've looked around and didn't really find much and on the few videos that I have found, despite the marvelous playing, the explanations were quite brief and not very detailed. Or does anyone here do it? Whatever, everything, anything that's good percussive guitar lessons/advice - toss it here!
