It Might Get Loud tells the personal stories, in their own words, of three significant rock musicians – The Edge (U2), Jimmy Page (Led Zeppelin), and Jack White (The White Stripes). The film revolves around a day when they first met and sat down together to share their stories, teach and play.

It is rare to find a music documentary that focuses on a single instrument rather than a band or a musician, but this is successfully achieved in It Might Get Loud. Three legends of rock of different generations share their backstories and insights into their deep affection for these strings.
