This beautifully designed photographic essay flows from Prince's sensational, unprecedented, record-breaking, sold-out 21 concerts in 21 nights at London's O2 Arena in 2007. Juxtaposing his dueling worlds of music and solitude, it will incorporate Prince's evocative poetry and lyrics to new songs and other selections, and 124 full-color, sumptuous, never-before-published images by celebrated photographer Randee St. Nicholas. As part of the dimensional experience, it will also feature "Indigo Nights," a CD capturing Prince's speak-easy, after-hours, raw, live after-show sessions of pure unadulterated jams. For the first time in 21 NIGHTS, Prince is seen behind the scenes. Randee St. Nicholas, renowned for her rich visuals, deft touch, and distinctive style, was given access to Prince's life and career, providing a nuanced and unparalleled view of the artist, accompanying him onstage, backstage, and into his sleeping quarters. "Indigo Nights," which includes the live version of the song "3121," will not be available in any other format.
