U2 hits the iHeart Radio Festival (23 Sept)

"One of the reason's for U2's longevity is that they are not in music for entirely selfish reasons. I don't want to make them appear as evangelists, which, of course, they were seen as by some sections of the music media in the early 80s, but I do believe that they really think what they do serves some greater purpose than simply filling their bank accounts." - Brian Eno, 2009
