I feel like, in many ways, Billie Holiday's still very under-appreciated as an artist. People focus on her voice, and all of the very recognizable vocal things that she does, which are great. But I wanted to, with this project, start the conversation again about her as a radical feminist, as a civil rights activist - taking a stance. And also just [her] being a non-conformist.

For me jazz is kind of an extension of hip-hop. Kind of the sad thing is that a lot of jazz people just listen to jazz, and a lot of hip-hop people just listen to hip-hop, and there's not a lot of crossover, unfortunately.

Chico Hamilton told me, "The first take is important in jazz because that's where the real emotion is." That's your true response to what's happening, and everything else after that, your brain is involved because you have something to reference.

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.

I've sort of realized there's a definite pattern to my output at this point: there's an album that everybody sort of loves, that's a real balance between the old and new, like The Dreamer or No Beginning No End, like a blend of jazz and hip-hop, or r&b and soul and hip-hop.

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.
