Once something is memorable, it's living and you're using it. That to me is the foundation of a creative society.

What came up at age 49 is I realized that of all the things I'm interested in, the thing I'm most interested in is figuring out what makes people tick, why people think the way they do, why they act the way they do. And I realized that music is such a great way to investigate why people do what they do.

The tango is really a combination of many cultures, though it eventually became the national music of Argentina.

As a musician I'm kind of nomadic, Waldo-like. I show up in different places, and I'm witness to unbelievable things.

Passion is one great force that unleashes creativity, because if you're passionate about something, then you're more willing to take risks.

There's a part of me that's always charging ahead. I'm the curious kid, always going to the edge.

I really would like to be involved in things and to understand things, and in some ways you've got to be careful what you wish for because I feel very, very blessed to have such an interesting life and to be able to have little snapshots of lives of people from many different parts of the world.
