It's very simple, but really smooth and cool. I shared it with all my rumba buddies, and my main teacher said, "yeah, I've seen it, but I dare you to play it fast!" And he's right, they didn't play it very fast at camp,, but it's much sweeter than the "normal" columbia we've all heard. It's nicer and slower like a Bembe.
I've also made a master CD of the song class and have copies of the songs from 4 orishas with Bata, and 3 songs to Guaguanco, if anyone's interested in singing. IM me with your address and I'll send you copy. And of course, this is only for study purposes..
