It Might Get Loud, a documentary featuring three electric-guitar legends and spanning three generations, is an insightful documentation of passionate musicianship. Following U2’s The Edge, Jack White of The White Stripes and The Raconteurs and Jimmy Page of Led Zeppelin (PICTURED ABOVE, LEFT TO RIGHT)—who meet at an empty soundstage —the film is a gold mine of thoughtful, perspective-laden looks at the three men and their art. Page visits the hallowed halls of the English manor Headley Grange, where Led Zeppelin’s Stairway to Heaven took shape; The Edge strolls through the Dublin high school where U2 began playing together as teens; and White composes his signature blues-tinged, foot-stomping rock in a Tennessee farmhouse. The soundtrack (you’ll want every song) is a winner. Amid concert footage, impromptu jams and musings on rock ’n’ roll (Of the movie Spinal Tap The Edge says, “I didn’t laugh. I wept because it was so close to the truth.”), the three talk shop, show off their instruments and do what they love best—spend time with their guitars and spend time making music. Directed by Davis Guggenheim. Opens August 14.
