Book excerpt: Cheney (ethnic studies, California Polytechnic State U.) considers the political expression of rap artists within the historical tradition of black nationalism. Interweaving songs and interviews with hip-hop artists and activists including Chuck D of Public Enemy and Rosa Clemente, manager of dead prez, Cheney links late 20th- century hip-hop nationalists with their 19th-century spiritual forebears and challenges the perception of hip-hop as simply sexist or misogynistic.
