Frogman, it is more "logical" that you are right.
"Moreover, just as there are “retro” Jazz artists still playing Ragtime and Dixieland, I have no doubt that there are drummers in Africa that can still play in the style of those centuries old drumming traditions."
This is probably true, but I only see and hear what is current in Africa, plus they seem to want to get closer to what's popular, while I hear ancient rhythms from Brazil and Cuba as well.
