Slick documentary that acknowledges the ties between three generations of electric guitar rock music virtuosos: "Led Zeppelin"'s Jimmy Page, "U2"'s The Edge, and Jack White of the "White Stripes" (and numerous side projects). Director Guggenheim gets the three together for the first time at an L.A. soundstage jam session and then profiles them individually (in London, Dublin, and Tennessee), including how the guitarists developed their signature styles. Numerous performance clips and concert footage are included.
