Frogman, on the Afro-Cuban Tutorial you posted, Ignacio Berroa discussed all the African rhythms that exist in Brazil, South America and Cuba.
Ages ago, I initiated this very subject. Before slavery, Africans lived in peaceful villages all over the continent; each village had it's on dances and style of drumming and Rhythms. Africa is a big continent, while villages are relatively small groupings of people; that means there were a multitude of villages with many different rhythms. I stated that many of the rhythms of Africa are no longer on that continent; those rhythms left that continent with the slaves on the slave ships and can only be found in this hemisphere.
There are very unique rhythms in Brazil, and I don't mean that Rio Samba thing, these rhythms emanate from the interior of Brazil where slaves ruled for a period of time.

As I stated, there was a multitude of villages, that's what enabled the more powerful kings to capture people after a price was put on their heads.
"Kunta Kinte (roots) was born circa 1750 in the Mandinka village of Juffure, in the Gambia. He was raised in a Muslim family."
I went on a tour up a mountain in "Cap Haitian" Haiti, and we stopped to rest and have refreshments at a clearing along the way. Not far from where we were, there were some kids playing; the oldest was 12 or 13, there was a total of 5 kids as I remember. The reason this tiny incident sticks in my mind is because it was not a part of anything, just some kids playing and entertaining themselves as kids do.
The oldest kid picked up a shovel lying on the ground, propped it against a tree, grabbed two rocks, one for each hand, and began beating out rhythms on the shovel while the other 4 kids danced. It was so hypnotic; they moved like their bodies had no bones, while the older kid beat out the rhythms. I don't want to attach the word "voodoo" to those rhythms, because to those kids, they were simply the rhythms they danced to, and how they danced, like their bodies were without bones.
