What happens when three world-famous guitarists get together and talk about music? Well, it might get loud. An Inconvenient Truth director Davis Guggenheim got to be a fly on the wall when Jack White, The Edge and Jimmy Page got together on a soundstage and, apparently, told each other everything they know. The entire experience is captured in It Might Get Loud, the documentary coming into theaters August 14.

Yahoo! Movies has posted a new trailer for the film, which might give some of the less hardcore rock fans a notion of why they'd want to see this. Yes, there seems to be a lot of geeky chatter about chord progressions and amps, but there's also a lot of rock and roll history in here, and three big personalities coming together in one place. Check it all out in the embedded trailer below.
