Bono performing Bullet The Blue Sky

"As our style developed—and it did, slowly—it was an evolution rather than an intellectual decision to go this way. And the echo helped along the way. And now, in retrospect, I’m learning more and more about playing less. That’s a whole education which I’m going through now. Back then, it was literally that we played all the time. There were very few gaps. It was more of a tapestry of sound rather than spaces and holes. Just a whole wash." - The Edge, 1986
