Gentlemen, Gentlemen,
Let's not move so fast of this 'African" stuff. It's not as simple as you are making out.
The most important and significant thing said so far, is that there is no African, in African-American music. It is unquely American. This includes Jazz.
Cultural forces don't move that fast. More like glaciers. The only possible African influence would have been from people arriving here directly from Africa during the slave trade. Importation of slaves into this country ended in 1810, if I recall correctly.
Once here, the influences were Euro-American. Primarily music inspired by The King James version of the Holy Bible.
Please don't make me have to fight off VooDoo!!! And to think, someone once chastised me for saying you have to DEFEND the music! :)
And finally, O-10, this drum nonsense, is just that.
Cheers
