African Musical

Any suggestion for a presentation on African American Music?

I am in a college class called "African traditions American Musical "and have presentation to do almost everything to do with Afro-American. Some people is the gospel, neo soul and other even just a presentation in one person, but I am completely drawing a blank, and I do not want to take something obvious and do the same thing as someone else.
