Gamelan Percussion is so cool

I found another cool video, only this one happens to be a gamelan orchestra in Indonesia. I love this. If you watch the metal "xylophones" (I don't know their official name), they are playing with one hand a muting the notes in their other with quite a bit of speed. As far as I can tell there isn't a conductor, either. So they have somehow instilled a great sense of pulse in these people, even with what seems like meter changes, too. I wonder how, and if that can be applied to an American group. I may have to look into that.
