'Loud' rocks guitar documentary
Davis Guggenheim to unveil film at Cannes
By PHIL GALLO:

Davis Guggenheim has completed filming on a documentary that will look at the story of the electric guitar from the point of view of three significant rock musicians: the Edge, Jimmy Page and Jack White.

Guggenheim, director-producer of "An Inconvenient Truth" and "Deadwood," directed and co-produced "It Might Get Loud," which Thomas Tull financed and produced. The Little Film Co. will represent the pic in Cannes.

Led Zeppelin's Page, U2's the Edge and White, leader of the White Stripes and the Raconteurs, were chosen for their impact across three different generations -- from Page's 1960s days as a session musician and a member of the Yardbirds into the Edge's unique sound developed in the '80s through White's current work. Each explains and demonstrates how he changed the sound of the electric guitar to suit his own style. Pic includes a jam session featuring the three guitarists.

Pic was shot in London, Dublin, Nashville and Los Angeles. Bert Ellice and Hyperion Entertainment are exec producers; music supervisor Peter Afterman of Inaudible and Lesley Chilcott, a producer on "An Inconvenient Truth," are also producers.
