According to The Associated Press, the latest Guns N' Roses project is not an album, a video or a book: It's all three.

The band has completed a multimedia edition of the biography Reckless Road, in which author Marc Canter tells of the making of Guns N' Roses' multimillion-selling debut Appetite For Destruction.

The video book goes on sale today and was produced by Vook, an Alameda, Calif.-based digital publisher.

Vook says with 40 minutes of candid video interviews and 200 images, Reckless Road is the definitive book about the early years of Guns N' Roses. Enhanced with seventeen great videos of interviews with the band and their associates, Reckless Road presents the definitive picture of the band when it was living on the edge of greatness and chaos. Written by Marc Canter, Slash's best friend of 30 years, Reckless Road offers unprecedented access to hundreds of never-before-seen photos and memorabilia from the early years of one of the greatest rock band of all time, Guns N' Roses.

It has a suggested price of $4.99 and can be downloaded from Vook's website, or from Apple's iTunes.
