U2 in Glasgow

"You could be in a club right up close, and the band gets up there like 'get a load of me, here's another thought which I had that you probably can't understand.' All of these people saying that rock bands don't go to the arenas — that's all a bunch of bull. It starts with emotional proximity, and you can use technology to create physical proximity. It goes back to (U2) being in the clubs, wading into the audience with a white flag, and getting into a fist fight because of it." - Bono, 2015
