I really like the complexity of jazz, the emotional depth; I feel like there's no other music that's really as satisfying as jazz.

When I start working on a new album, I kind of stop listening to a lot of outside stuff just so I can kind of focus.

If you look at the other singers of Billie Holiday's time, they were really trying to entertain. They were trying to make people feel good. They were singing fast - and she was singing the blues.

All my stuff is pretty seamless - like now, while I'm touring [Yesterday I Sang The Blues], today I'm going to go in the studio, I'm writing my next one. For me it's continual.

I'm working with a producer, Scott Jacoby, who co-wrote "Trouble" off No Beginning No End. Without giving away too much, it's a definite pop/r&b vibe, pretty strong melodies, and definitely about songs.

I go by the "Miles Davis school of production and band-leading", where you pick the best musicians you can, you provide them with a minimum of direction, and you just let the music happen. I've seen it work time and time again.

Jason [Moran] and John [Patitucci] and Eric [Harland] knew it was a Billie Holiday tribute. I'm sure they assumed it was going to be like another singer date, where we just have a bunch of charts and they write them down and they got paid and kind of moved on. There's nothing wrong with that, but it's not what I intended.
