You can build up expectations for a song before you record it, and then it's like nothing's good enough in the studio.

I still play solo shows. And some of those shows are still some of the best, most gratifying shows.

There is something comforting about going into a practice room, putting your sheet music on a stand and playing Bach over and over again.

Some of your best songs come from a desperate attempt to escape, so sitting in an airport for hours I can just start pulling out little fragments of songs from my head. A lot of times a melody will just occur to me and be my companion for a couple of months.

The orchestra's an amazing instrument, but I don't want to just arrange my songs for it. I think that might be kind of boring and a little bit overdramatic, perhaps. I'm still just having too much fun doing it my way, for the time being.

I think jazz was just seeking respect and validity because a lot of people didn't believe it was a viable art form, and then they got a lot of attention in Europe. A lot of bands that can't catch flies in the US have these followings in Europe, [but] it's less and less the case. American audiences are way more sophisticated and adventurous than anyone thinks that they are.

This might be a controversial thing to suggest, but in a quest to understand and relate to terrorism or school shootings, sometimes it feels like it's real, the appeal. As we've seen with ISIS, it's not always the devout who are getting into it; it's just people looking for a sense of belonging. The more they feel they're up against, the more intensity the cause has. It's an epic clash of cultures, and both sides are playing that up, but it's human beings disaffected, detached, and lonely.
