Mississippi since the civil rights movement?

(Cross posted to History Readers: Clio's (Pleasure?) Palace)

I recently read John Dittmer's excellent Local people : the struggle for civil rights in Mississippi and Neil R. McMillen's Dark journey : black Mississippians in the age of Jim Crow is on my up next shelf. But there seems to have been very little written on the state of Afican American rights and life since the civil rights movement. Is anyone aware of a good book on this recent history?

Not sure if I should post this to a separate thread, but it's a related question - I would be interested in a good book on the role of music in the civil rights movement (I am thinking of things like Nina Simone's "I wish I knew how it would feel to be free" and possibly "The revolution will not be televised")
