I'm listening to a lot of Drake, and a lot of Frank Sinatra just because it's his centennial also. I'm going to be doing some tributes to him this year. I love that Beck album. It was funny to me because my two favorite albums of the year were definitely the Beyonce album and the Beck album.

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.

There used to be a club in new york called Bradley's - I've never been there, it closed in the 80's - but I used to study with Junior Mance, and he would tell me about Bradley's. It was a very important place for a generation of jazz musicians in New York. It was really all about pianists there.

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.

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'm pretty much always planning two albums ahead.

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."
