Then, you know, the other more-traditional role of the producer in, like, the kind of Quincy Jones sense is kind of part arranger. So you're coming up with, like, these - you hear these songs that are quite bare-bones, and you dream up what's the band doing? What's the rhythm section doing? What's the guitars, strings, pianos - that sort of thing. It's almost like a little toolbox.

You just pick up a little bit of whatever the ones you think are appropriate, and you try and, you know, combine them. And then you bring in other people that are great for the things that you're not so good at.

I never studied jazz technically; I just know and love the music.

I think that where it came from and the initial birth of it - it did come out of a jam at Bruno's studio, you know? He was playing drums. And Jeff Bhasker, who co-produced the record with us, is on synths, and I was playing bass.
