Last Night a DJ Saved My Life was the first comprehensive history of the disc jockey, a figure who has become a powerful force shaping the music industry–and since its original publication, the book has become a cult classic. Now, with five new chapters and over a hundred pages of additional material, this updated and revised edition of Last Night a DJ Saved My Life reasserts itself as the definitive account of DJ culture, from the first record played over airwaves to house, hip hop, techno, and beyond. From the early development of recorded and transmitted sound, DJs have been shaping the way we listen to music and the record industry.
