This book explores the links between hip-hop and rock music. Reynolds focuses on two streams: white alternative rock and black street music. He captures the peculiar dance between white bohemian rock and black culture, how they converge at various points and then take different paths. Through interviews he has conducted as a leading music journalist over the past twenty years, he tells a story of musical rivalry that has never been told before. His approach is similar to that of "Rip It Up and Start Again": a cultural history narrated through the music we love and the stars and movements that have shaped the world we live in.
