The year 1979 was a seminal watershed moment in rock music. The year saw the release of Pink Floyd's The Wall, David Bowie's Lodger, Led Zeppelin's In Through the Out Door, Bob Dylan's Slow Train Coming, Fleetwood Mac's Tusk, Elvis Costello and the Attractions' Armed Forces, Joe Jackson's Look Sharp! and I'm the Man, Stiff Little Fingers' Inflammable Material, Gary Numan/Tubeway Army's Replicas and the Pleasure Principle, Joy Division's Unknown Pleasures, the Jam's Setting Sons,the Clash's London Calling, and the UK 2-Tone phenomenon. It also saw a slump in album sales, a resurgence in single sales, and the peak and bloody death of disco. Now, with the help of new and exclusive interviews with artists and producers, New Waves, Old Hands, and Unknown Pleasures tells the varied, vibrant, and often unexamined story of popular music in 1979. It reveals the stories behind key recordings, traces the trajectories of commercial and artistic successes, and explains the musical and socio-political context behind the sounds of the day.
