U2 hits the iHeart Radio Festival (23 Sept)

"My ambition for U2 has always been to push it to its limits - the most aggressive music ever made and, at the same time the most sensitive, different levels. I woke up a few months ago and found out I was Irish and that has made an impact and it's going to make an impact on the music. Because this is an Irish group and I'm realising that the very weapons you need are all around you." - Bono, 1984
