"Progressive rock is glabby and dizzy. Unfortunate there is a lot of progressive rock on the rise, sadly. Progressive, if you mean innovation if you mean discovering new ground than I like the term. But progressive rock recalls for me the seventies, long solos and evenworse haircuts. But I can't really point a finger because in the eighties I had a haircut that inspired a million second division soccer players. We've cut our hair for this record, so it can't be too progressive rock." - Bono on Pop, 1997
