It was a blind buy for me and I have to say I enjoyed it more than I thought, but it also was not what I was expecting. I, too, was hoping for a little more of the guys playing together, but this is not a concert disc; it's a documentary of three musicians from three eras and their story of how they came to where they are musically.
J is right on a lot more being in the extras and yes, Jack does seem to love the camera. I have to admit that after watching this I have a much greater appreciation for his work, how he listens and strives to be a better musician that wants to learn and grow. It's inresting how all of them seem to trace back to Blues as their big inspiration. The Edge's face and especially Jack's when Page starts playing some Zep is almost worth it.
If you love music, especially electric guitar, I would say buy it.
PS I thouhgt that kid with Jack was his son, too, until I watched the extras!
