I think it’s fun to wonder about what bands our kids will be listening to in 20 or so years. I’d bet a fairly large sum that the music of Led Zeppelin, U2 and The White Stripes will be deeply embraced by our next generation. In It Might Get Loud — a documentary film that captures the first meeting between Jimmy Page, The Edge and Jack White — three guitar visionaries share stories. If these three got together and discussed broccoli for 2 hours, I’d probably still see it.
