A gift to guitar geeks, It Might Get Loud sets up a meeting of three generations of seminal guitarists: Jimmy Page, The Edge and Jack White. Yet for the most part, director Davis Guggenheim (An Inconvenient Truth) extends its appeal to anyone with enough musical interest to be intrigued by the subject.

A gift to guitar geeks, It Might Get Loud sets up a meeting of three generations of seminal guitarists: Jimmy Page, The Edge and Jack White. Yet for the most part, director Davis Guggenheim (An Inconvenient Truth) extends its appeal to anyone with enough musical interest to be intrigued by the subject.

He opens with one of the film's best scenes, in which White crafts a workable, one-string guitar in an old barn out of found wood, nails and a Coke bottle, while a few disinterested cows stand by. It's a funny, evocative illustration of the lo-fi approach White subscribes to, in which sound is most valuable when its creation presents a struggle.

Page strikes a similar chord as he recounts a career that could've been spent playing Muzak for good money if it hadn't needed the challenge of the Yardbirds and Led Zeppelin. They each have transcendent listening moments, Page with Link Wray's "Rumble," White with an old Son House record.

Given The Edge's long-standing love affair with effects, the third guitarist in the group is a bit of a fifth wheel. More clunkiness comes from contrivances of setting and situation and the inevitable comparison between guitars and women.

Nevertheless, it's a tight, entertaining package overall, and watching the trio jam on the lead from "I Will Follow" creates a kind of excitement you don't often feel at the movies.
