I'm not sure what I'm missing here, seems like very fast hand tapping, weak tones and very little rhythmic swing to get a feel of.
The current top player in my opinion.
http://www.youtube.com/watch?v=8r0A3mllzUcThe original was Armando Peraza, there's a video somewhere of a famous solo he performed with Santana, speed is pointless if you aren't maintaining a strong musical groove unless you are trying for the guiness book I guess, most of Peraza's greatest work was way before youtube was even a concept so you have to listen to 'Los Ritmos Caliente' for example.

PS... of the two videos here I way prefer the second guy, but his slaps are weak.
