It Might Get Loud
I just finished watching this documentary with Jimmy Page, The Edge, and Jack White. I'm neither a guitar fancier nor a movie critic but found this very informative and entertaining. The movie has to with each of their histories with playing the guitar and their approach to music and how the guitar fits in. Three generations of guitar music and playing with a lot of dialogue and insight into music, writing, and playing. If you get the chance check it out. As a bonus you will even get the opportunity to see Meg White playing the drums.
