By the end of the 1970s, Sparks' quirky art rock had run its course; 1977's Introducing Sparks was their first real dud. So, they did what all great artists do: reinvent themselves. Produced by Italian-disco maestro Giorgio Moroder, the electronically tinged No. 1 In Heaven is as gorgeous and prescient as it is brainy and acerbic. Over sweeping arpeggiations and pulsating 4/4 beats, the Mael brothers spin yarns about social Darwinism, crass commercialism and sexual obsession. In a lot of ways the album mapped out the '80s (from new wave to synth pop) before the decade even began.
