The self-styled definitive history of the humble art of spinning plates of vinyl, the Last Night A DJ Saved My Life steps up to the turntables with worthy pretensions. The work of journalists Bill Brewster and Frank Broughton, who, between them, have worked on The Face, i-D, Rolling Stone and Musik, they certainly know their deep house from their speed garage. But while Last Night A DJ Saved My Life is an impressively knowledgeable compilation of information, they never quite decide whether this is an intellectual resource, a complete history, or if they're playing these records just for kicks.

So in the preface fun is poked at abstract nonsense about postmodern intertextuality and the pair thunder into well-reasoned, impassioned debate about the DJ being a modern-day shaman--pulse-racing stuff, which makes it all the more uncomfortable when it segues into an unremittingly dull chronological history of the invention of the record deck. The pace quickens with an excellent chapter on Northern Soul, and in hot pursuit follow impressive histories of the reggae, hip-hop and disco genres. But then Acid House, perhaps Britain's most important musical evolution ever, is given short shrift and techno is dismissed over a mere ten pages as house's swotty offspring. The term definitive, it seems, has been faded out of the mix.

The Last Night A DJ Saved My Life is no Bible for the penitent vinyl worshipper and its difficult chronology makes it an uncomfortable read. Still, if you think that Northern Soul records were made in Leeds and disco began with the Bee Gees, there's a wealth of knowledge here that'll put you right.

To celebrate 100 years of DJing, Bill Brewster and Frank Broughton have expanded and updated their classic account of the history of the disc jockey. The DJ was born on Christmas Eve, 1906 when Reginald Fessenden became the first person to play a record over the radio. A century later and the DJ is the central figure in popular music. From these humble talking jukebox origins to today's DJ superstars earning rock star salaries with a fanbase to match, the history of the DJ is fascinating and unpredictable. The story of these unlikely cultural icons takes the reader through the swinging sixties, through the sequinned revolution that was disco, via hip hop and house to mass-market global domination.

Bill and Frank's classic chronicle digs deep to find DJing started in 1906, the Nazis invented clubbing and Jimmy Savile should be a hero to all. Arguing that DJs not musicians are pop music's true revolutionaries, it details with love all the scenes that matter. The new edition is beefed up with entirely new chapters covering techno, acid house, Ibiza, jungle, UK garage and cosmic disco.
