Fantastic
I can't recommend Paul Gilroy's work enough. This one is based on lectures given at Cal Irvine, whereas Black Atlantic (which I have yet to read) and Against Race (which I have also read and would highly recommend) are full length books.
I learned one more reason to dislike Larry Summers: that he considers Africa to be "underpolluted." !?
I am a musician and I think that Gilroy is one of the best contemporary writers on popular music, although that is not his primary focus. He moves well between different genres of cultural production. I like that he doesn't over-privilege literature at the expense of films, tv, music. Against Race even features great readings of things like tea bags and bars of soap!
