The newest, most updated book on Prince available today—now updated with information about the afterlife of his work following his untimely death. Famously reticent and perennially controversial, Prince was one of the few music superstars who remained, largely, an enigma—even up to his premature death on April 21, 2016. A fixture of the pop canon, Prince is widely held to be the greatest musician of his generation and will undoubtedly remain an inspiring and singular talent. This revised and updated second edition of this meticulously researched biography is the most comprehensive work on Prince yet published. Unlike other Prince books, this one eschews speculation into the artist's highly guarded private life and instead focuses deep and sustained attention exactly where it should be: on his work. Acclaimed British novelist and critic Matt Thorne draws on years of research and dozens of interviews with Prince's intimate associates (many of whom have never spoken on record before) to examine every phase of the musician's 35-year career, including nearly every song—released and unreleased—that Prince has recorded. Originally released in the UK in 2012, this revised and updated second US edition of Prince includes updated content regarding work released and made available after the artist’s death.. This astonishingly rich, almost encyclopedic biography is a must-have for any serious fan of Prince.
