more than 200 interviews with friends, ex-girlfriends, bandmates, recording engineers, bodyguards, personal assistants, wardrobe designers and hairdressers, accomplished music writer John McKie examines the life of this musical polymath with the help of many of the people who knew him best. Family members and friends discuss his childhood when he learned to master several instruments, there is new information on how he made the soundtrack to Purple Rain, the full story about why he decided to stop using his name, the now legendary Super Bowl half-time show and that guitar solo at the Rock 'n' Roll Hall of Fame which has been viewed on YouTube 100 million times. McKie also dives into the personality of the man: what made him laugh, the way he hired and fired colleagues, what he was like to live with, how his relentless drive to make music led to him recording for hours without sleep, how he changed his car stereo to road test his new hits and even booked his guitar and album sleeves their own seats on flights. Prince: A Sign o' the Times is the most comprehensive book ever written about one of the most enigmatic and talented pop stars of all time.
