Academy Award-winning An Inconvenient Truth director Davis Guggenheim focuses his probing lens on a subject that's decidedly less urgent but no less fascinating with this look at the electric guitar featuring Led Zeppelin's Jimmy Page, U2's The Edge, and The White Stripes' Jack White. Growing up, all three guitarists realized their rebellion through music: Page was attempting to subvert the sugary sweet pop music of the 1960s, The Edge was hell-bent on making the naval-gazing guitar solos of the 1970s a distant memory, and White used his screeching strings to buzz out the droning bass machines of the 1980s. Later, Page makes way for Headley Grange to revisit the birthplace of "Stairway to Heaven", The Edge digs out the original four-track rehearsals for "Where the Streets Have No Names" in Dublin, and White expresses his exuberance for revered bluesman Son House - all the while displaying their deep love for their instrument of choice by permitting the viewer a rare chance to see them refining as-yet-unreleased material. When the trio comes together for a landmark jam session, their spectacularly diverse styles and instruments become just as apparent as the shared passion that binds them all together.
