I’ve never just sat down and said, “Okay, let’s make this whole album together.” It’s always a very gradual process. That’s what it was with Ella [Marija Lani Yelich-O’Connor, Lorde] when we started working on Melodrama. There were a lot of early recording sessions on that album where the box was so big of what it could be, and we just really defined it slowly. And that’s my favorite way to make records: to have a partner, whether that partner is another artist or an imaginary person in your head [laughs]. Then you just set out this entire body of work that has all the things you love about albums. It’s too big to fathom, so you just very slowly push that boulder up a hill.
