If you're interested in studying this further iirc Gunther Schuller discussed it in "Early Jazz" (one of the first books about Jazz History that actually isn't terrible from a musicological point of view) and Nicholas Cook also discusses it in "Music, Imagination and Culture" (which is an amazing book). Both of those will give you a "Western" perspective of the influence. I don't know a great reference I can recommend from an African point of view unfortunately.
