"I was opened up by grief. I was the typical troubled teenager. There was a moment in punk rock when you couldn't have heroes. It was the end of progressive rock. An anti-star stance. I had to take off all the posters from my wall in my bedroom but I couldn't take down my David Bowie poster. The grief following my mother's dead there was no doubt that opened up a hole in me, that I've tried to fill with music. And I did fill it with music but I could have filled it with other things." - Bono, 2022
