I would love to hear some tracks from Pop live, esp. Mofo! Now THAT'S a rocker!
As for what kind of band U2 is, Bono has himself said on many occasions they "come from punk rock". Although I (a fan since '83) personallyconsider them rock, they have expanded their sonic repertoire in a variety of ways over the years, and that's what keeps them interesting. If they hadcontinued with the same sound from any of their excellent earlier eras, they would have ultimately become one-note, boring, and irrelevant. Instead they shakeit up and do something different every few years, and I've only been disappointed twice (w/ Behind and Bomb). Thank goodness they DO shake it up, becauseafter Behind and Bomb, I anticipated NLOTH cautiously... and I'm happy to say it restored my faith that U2 still desire to heed their muse.
