U2 in Slane Castle

"At times we were surprised by the music that we would make. I can remember how, after recording our first album, we were listening to it, really loving it and being proud of it, but also thinking, Where did that come from? I didn't know how it had happened. That was a funny feeling. Some of it seemed like magic. It just kind of came together. We operated a lot on instinct and everything happened really fast. There was a certain kind of freshness. A song like I Will Follow, still stands up as a great song. It still sounds wild to me." - The Edge, 1999
