Against the odds, 90125, released towards the end of 1983, was Yes' best-selling album. Yet it was never intended to be a recording by one of the 1970s rock dinosaurs, but a combination of commercial expediency and luck saw an album by a new band called Cinema – featuring Yes stalwarts Chris Squire, Alan White and Tony Kaye alongside talented multi-instrumentalist Trevor Rabin – become Yes following the last-minute recruitment of vocalist Jon Anderson. A US number one hit single, 'Owner Of A Lonely Heart,' led to a triple platinum record and a massive world tour, giving this band a new lease of life in the 1980s.

Featuring new interviews with several of the main protagonists, including Jon Anderson and Trevor Rabin, this book traces the story of the album from its rudimentary demos in 1981, right up to the end of the world tour in early 1985. 90125 is reviewed in full, and the book also includes a detailed look at the somewhat complex and contrived process that created it, followed by an examination of the album's legacy and remarkable afterlife.

The 90125 story is possibly the most astonishing in this legendary group's nearly six-decade history. This is how it happened.
