About 4 years ago, I saw a web site promoting some guy, with a streaming video, that played the guitar in a way that the melody wasn't all that important. The really amazing thing was that he made all percussions by tapping the guitar, wharever

it wasnt like flamenco, pounding it with the ring finger or the thumb or anything like that, he pounded the guitar with his palm, with his fists, taked advantage of the clapping sound made when you do tapping, but so that it sounded "percutive", making percussion with both left and right hands

really good percussions, african-like and not "sporadic" like flamenco "golpeados", intended not to percuss and mark the rythm, but to florish the melody
these where all the way around, it sounded really cool

at the same time, it wasnt just percussions, like "drum guitar", there was also a really nice blues-rockin melody he did by tappin' , just legato, or sliding chords around

whats the name of this style ? i've been searching for tutorials in the net but found not 1, can anyone refer me on this please?
