Have you felt like anything’s changed since winning?

I haven’t felt any shift from the receiving end of my life. This sounds crummy to measure yourself this way, but I have a lot of impostor syndrome in my life. Do I deserve to be here? It’s definitely present at a place like the Grammys. So, that lifelong dream has happened. Great. Let me focus on different things in my life. I’m not gonna say, “we’ll be back in two years winning again.” I already got that T-shirt. Check it off.

I saw you did a foot peel after the show.

It’s so gross. It’s a gradual process of two weeks. You put your feet into a chemical solution and then the skin sheds like a snake for two weeks. It’s so gross. Every time I take my shoes and socks off I have to peel it away. It’s such a good example of where you get to when you’re in a relationship with someone — I’m a year and a half in with my girl and this is where we’re at.

I only know about that because my friend told me to watch [Finneas's girlfriend] Claudia’s videos, by the way. How do you figure out how much you're going to share of yourself, especially now that there’s so many more eyes on what you’re doing?

I love her videos. I feel like I was pretty elusive, and now there’s real documentation of my life. It’s a good thing, but it’s definitely an adjustment. She’s really respectful and intuitive when I don’t want to be filmed. She’s not always gonna keep the camera rolling. Her videos aren’t salacious like a lot of YouTube channels are.

The benefit is I never film anything — I don’t have a philosophy about it. But it’s just not a strength of mine. As much as I’m a creator in music, I’m not a photographer. She’s got an eye. So especially when there’s a momentous occasion like Coachella, she documents that beautifully. I’m grateful for that, because if it were left to me, there would be no evidence.

So you’re the producer of the year — but who were your producers of the year?

Louis Bell was the producer of the year. Motherfucker did everything. And he’s such a cool guy. Before the nominations I was like, “of course Louis Bell will be nominated. I might be, but Louis will win it.” And then he wasn’t even nominated. Bizarre. He means a lot to me. Ricky [Reed] did a lot of cool stuff, and I love what Rostam did on Clairo’s record. Ariel Rechstaid did a great job on the Vampire Weekend record. And I love James Blake’s album, and all the production on it.

Do you agree that the best kind of producer is the one who makes the artist sound most like themself?

I definitely agree. That’s how I rank producers, and it’s a criticism I’ll throw at people who are very talented but are not invisible. I don’t mean physically invisible, but musically. You should work with an artist and make their best record, not your best record with them singing on it. That’s the goal, always. Hopefully people see that when I make a record with another artist. If I’m recording with Tove Lo, I want that song to sound like a Tove Lo song, not a Billie song.

When I started producing Billie’s stuff, I wasn’t being asked to work with anyone else, and people would say “that’s the FINNEAS sound.” No, that’s the Billie sound. I’m just the dude working on it with her, and just because I work on someone’s record doesn’t mean they’re going to sound like her.
