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 don't get writer's block. I don't try to write anything; when something comes, I write it. I just practice and when I get an idea I write it down.

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.

I also tried to focus on songs that Billie Holiday wrote, songs that she had a hand in shaping, like "Strange Fruit"; songs that were written for her or songs that she wrote herself, like "Fine and Mellow" or "God Bless The Child."

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.

There's a more experimental album that follows that, which is like Black Magic and While You Were Sleeping. Then there's a return to jazz, For All We Know and Yesterday I Sang The Blues. It wasn't like a planned thing, I just kind of realized it when I made a list of my albums. Like, oh wow, this is exactly what I did before.

For better or for worse, I think my approach to jazz is very traditional, in one sense, but is [also] very out of fashion today. It's about the musicians, and it's about that magic that happens in the moment.
