U2 in Berlin

"Always, as a band, we never really liked the heavy sounds that were happening in the mid ‘70s. We were really excited by a lot of the stuff that came through in ’76, ’77, which was when we really started to play together in earnest. Up until then, we listened to the Stones, early ‘60s stuff, but then we got totally captivated by what was going on in New York and London, mainly." - The Edge, 1986
