U2 in London

"If I'm honest, there is something about the sound of the record that is a little too organized. That's what happens when you're too long in the studio. But it's called 'Songs of Innocence' for a reason. That's the challenge with this band after all these years — songwriting — not sonic fireworks or experimentation. Can we write songs that truly hold up?" - Bono on Songs of Innocence, 2015
