Nelson George, possibly the most underrated music writer of our time, has done it again. "Hip Hop America" is a worthy successor to his classic "Death of Rhythm & Blues". If you're some [like me] who has never taken rap music seriously before, Nelson will make you sit up and take notice. Like Bill Rhoden in the NY Times, Nelson George may not be someone you always agree with, but he is a writer who commands respect and attention. His recent nomination for the National Book Critics Circle Award for "Hip Hop" is all the evidence you need.
