"Some artists become dull when they stop drinking or drugging, but Adam's not one of them. He's his old self. He loses none of his rubber-band-shooting,water-gun-squirting, public-disrobing spirit when he doesn't drink."
The cover art for No Line on the Horizon is a photograph of Lake Constance, taken by Japanese photographer Hiroshi Sugimoto; titled Boden Sea, it is one of 200 pictures in his Seascapes collection. The image was the inspiration for Bono's lyrics on the track "No Line on the Horizon".
