Prince/ the Artist Formerly Known As is working with Simon & Schuster to come out with a book in conjunction with his 50th birthday.

The book will be entitle 21 Nights and will be a tribute to his 21 sold-out concerts at London’s O2 arena last summer. It will feature a live session CD, poetry written by the singer, and never-before-seen photos.

Ever since prince entered the music scene with his 1984 album Purple Rain, he has been a force to be reckoned with, and if the book is anything like the performer himself, it promises to be interesting at the very least.
