I am just writing to make people aware of how great African music is. If you want a comprehensive analysis of African music, you should feel free to check out Mohammed Babangida's blog.
On the blog, Mohammed Babangida discusses the rhythmic nature of African music. He points out the call and response nature of many African songs, and notes the influence of the call and response method on African-American music today. What's also cool about Mohammed Babangida is that he discusses jazz forms such as Bebop or Bossa Nova and makes correlations between those jazz forms and African music.
So if you have an interest in African music, jazz, or both, then feel free to check out the blog. You won't regret it.
