"There's this image of the 'overground'. It was a time when everyone was all indie and grey and dull—the 'underground'. The overground was like coming out into the bright light of a modern city. It's an amazing place to be, walking around these modern cities like Houston or Tokyo. And the idea was coming out into that, embracing it, going after it."
- Bono about Zooropa
Dutch artist Herman Brood was asked by Bono to paint the cover of the Best of 1990-2000 compilation but died (committed suicide) before he could finish it.
