It Might Get Loud is a marvelous rock doc that manages to be wistful, tasty, and jam-kicking at the same time. In a high summit of electric-guitar fetishism, director Davis Guggenheim unites — and tells the separate stories of — three six-string wizards: Jimmy Page, the virtuoso fuzz-box classicist of Led Zeppelin, who is now an elegant moon-faced gentleman; The Edge, U2's mad scientist of sonic jangle, who shows you some of his tricks; and Jack White, the low-tech hell-raiser of the White Stripes, here to pay homage and also to represent, you know, the kids. The result is pure candy for the guitar hero in all of us.
