I do not dance to movies. But if I were to, or just tapping my foot to a beat, it would be to this documentary. Taking three excellent guitarists from different rock aspects and sitting them together was probably the funnest thing to record. Each story tells of hardship and beginnings that have never been told. Incite into what made U2, Led Zeppelin, and the White Stripes (and The Raconteurs) are described first hand by a founding member of their respected group. Its a simple film that ends with a clash of guitar jams. We all know the songs, this movie gives meaning to them.
