Rok, there's enough stuff that left Africa permanently during the slave trade to fill a library and a museum. While researching Cuba, I came across a master voodoo drummer who lives in Haiti. He has a chart of types of "exclusively voodoo drumming"", and what country that type of drumming came from. As ancient as it is, to pass history down from one person to another without writing, this is still being used in regard to voodoo. While he has all of the rhythms, he pointed out that many types can no longer be found in Africa, but reside in various countries in the Caribbean, and Bahia, where many types of voodoo drumming can still be found that are no longer in Africa. My ears told me that a long time ago. People in Africa are trying to move forward, and survive economically, while those over here who are steeped in Voodoo (which goes by many names) are leaning on that ancient religion which originated in Africa.
I'm not trying to diverge from the main subject, just pointing out something that's related.
Enjoy the music.
