Prince is to release a multimedia book about his 21-night residency at the O2 Arena in London last year, according to publisher Atria.

21 Nights, which is scheduled for release in September, will feature the singer’s poetry, as well as exclusive backstage shots captured by photographer Randee St. Nicholas.

The book will also be accompanied by a live CD comprised of new and old songs from Prince’s after show parties at the Indigo2.

The publisher said the book would come "elegantly sealed in a purple slip case with foil stamping and then shrink wrapped for protection."

Prince, who turns 50 in June, was the first artist to compile a residency at the O2 Arena – which was formerly the Millennium Dome.
