Pop/R&B superstar Prince is slated to publish his first book this fall entitled â21 Nightsâ according to Atria Books, an imprint of Simon & Schuster. The book is based on 21 sold-out concerts last year at Londonâs 02 Arena. Further described as a âphotographic essay,â â21 Nightsâ is expected to offer a rare glimpse into the life, lyrics and mystique of the artist through evocative poetry, lyrics to new songs and other selections. Nearly 124 full-color never before published images are expected to be featured in the new book by celebrated photographer Randee St. Nicholas. Adding icing on the cake, âIndigo Nights,â an exclusive CD filled with after-hours jams, will accompany the book.
