It's a very enlighting documentary with a lot of interesting sequences from pop history. It shows how musical influences work, how stilistic details are developed and how specific sound elements evolve. Also it gives insight into the different means of expression on the electric guitar e.g. by the way of using playing techniques or technology.
Jack White is one of the great eccentrics of our age. Page and the Edge are both brilliant in their own respect. Very interesting to see the incredibly different approaches that the three of them have on their instrument, but yet simultaneously sharing a mutual, universal love of music.
An intriguing look at the artistic process and a novel approach to the rock documentary, crafted with just the right amount of style by director Davis Guggenheim, all leading up to a very satisfying climactic jam session. A tremendously enjoyable documentary.
