Leading dance music writers Brewster and Broughton detail the visionary DJs who dramatically changed the course of music: from the very first nightclub DJs, to the founders of entire genres, including northern soul, hip hop, disco, techno, drum'n'bass and beyond. These are the obsessives, the playboys, the musical eccentrics who founded the craft of DJing, developed amazing techniques for performing with recorded music, and revolutionised the way music is conceived, created and enjoyed. They gave us new ways to have the times of our lives and forged a worldwide industry of nightlife and dance music. From unsung pioneers to overheated superstars, all the biggest DJ names are here.
