"It occured to me... look at the history of the band and then the Zooropa album... and looking at the history of The Beatles, and everything they'd done and learned, and then suddenly...Sergeant Pepper, which redefined the whole ballgame, and produced a different language, a different sound. And I think Zooropa achieves a new language for Bono to use - a language that's more his own, that he feels more comfortable with...
And musically, I think, we've defined, or found, a sound that we're entitled to use...It's a record deep with mystery for me.'
Adam speaking to John Waters for Race of Angels
'That's what I want it to be. Legal drugs! Why else would you buy an album these days? Have you read anything by (William) Gibson? It's sort of fucked-up sci-fi. And ('Zooropa') shows you what I mean when I say the textures on this record were very much influenced by what he writes about the future.'
Bono, August 1993.
