Here is a September 2010 AllAboutJazz interview with the very talented bassist and singer Esperanza Spalding. In the piece she discusses jazz and classical, her album Chamber Music Society, and being a musician and singer both. From the interview:
AAJ : Where does Esperanza the singer start and the musician end?
ES: That’s a good question—I never saw it like that, I guess. It’s not organized in my mind at all, really. I’m just going for what needs to be done, whether that means singing in a track or not, or I don’t know… You caught me off guard! It doesn’t really go with the way that I’m operating with my music. I certainly feel like all the elements, singing and playing, they’re really part of the same motivation, which for me comes out of composition: that’s my main passion, and what I really think rules everything else. It all comes from there.
