I come from a generation that was surrounded by popular music, but I don't know if anybody's ever going to move the ball forward as far and as fast as the Beatles did.

It takes one asshole to ruin the whole thing. That's it. One. The problem with the world is one asshole comes up with a really bad idea and now we're all taking our shoes off at the airport.

The art model of problem solving is incredibly efficient because ideology has no place there.There's only the thing and what the thing needs to be.

The best set was probably 'Bloody Sunday.' We had no money for extras and gambled on months of outreach to persuade the people of Derry to turn out and march for us on one single afternoon. And they did. In their tens of thousands. Seeing them march, their patience and their dignity and their commitment, I knew the movie would have a quality of truth.

I think that it's fear. The musicians themselves don't seem to know enough about why they're in the positions they're in, so they're afraid to lose those positions. If you're 22 years old and you can't believe you're even in the position to have a career making music, the first thing you're going to think is: Maintain. Don't lose it. And that's precisely what causes you to lose everything.

If you're not smart enough to know what Fidel meant during the Cuban revolution, that - when they were on the Granma - Fidel was already a rock star in Cuba, and how important that was to the indigenous population, then you're not paying attention.

I try to use other songs or bands as reference points - it seems like the easiest way to get across what are really differences of taste or opinion. If you know what kind of music somebody loves, then you can kind of figure out why they do what they do.
