It Might Get Loud (2009)

Rock icons -- Jimmy Page, the Edge and Jack White -- from three different generations come together to discuss the electric guitar and their musical influences. The men swap stories and crank up their instruments on an empty soundstage for a jam session. Along the way, they visit the majestic hall where "Stairway to Heaven" was composed, Jack White composes a song on-camera at a Tennessee farmhouse, and the Edge lays down tracks for a U2 single.
