I have nothing against reverb.

I think we're always looking for ways to inject a sense of humor into our music.

Love has always been the most important thing to me and the thing by which my life is guided.

It's important to recognize when a song remains important to you.

Usually, I get bored of my stuff almost immediately.

I don't really have any interest in recording at places that are institutionalized for recording.

Definitely for me and my sister, wherever we are the most comfortable is where the best music's going to be made.

We were a very crunchy, sort of hippie-dippy family.

Billie doesn't actually like recording sessions at all. We like making music together. She doesn't like going to some big studio and having them pretend to be a therapist for a couple hours. So by default, we always make the good stuff together.

Our mom cooks well, and we cook poorly. We try.

I'm not very interested in fame or notoriety at all - in fact, I'd be pretty bummed out if I woke up one day and I was, like, super, super famous. But the flipside of that is that I'm really passionate about my music, I'm really proud of it and I want it to be heard by as many people as possible, and I'm willing to embrace whatever comes with that.

As soon as you make anything that people like, you get all these new artists hitting you up like 'I want to sound just like Billie Eilish.' And I'm always like, 'Absolutely not.'

The way that we tried to approach every piece of music is, if the song had a brain, it would be aware of its catalog.

I am just fascinated by music and I want to know how to identify all the things I love about it; to me music theory is like learning another language and then being able to explain how much you love something more clearly.

I'm just obsessed with music I guess.

If you're thinking about all the possibilities of your life, there are extreme negatives, which you hope don't happen, and extreme positives, which you just aren't willing to think about because you think you'll jinx it.

I am not a very superstitious person, but I do believe in mental preparation.

To be honest, I've found so many more friends in the music industry than people I disagree with. I certainly haven't been made to feel like an outsider.

I'm not a control freak in that like I boss everybody around, but like a control freak and like, I like knowing exactly what I get to do that day and having a say.

People don't come to see a Billie Eilish show to come to see me. They come to see her. So I just try not to screw up too much on my instruments.

I've learned a lot from my mom and my dad. I learn a lot every time I watch Billie perform.

I really always wanted to be an adult. I didn't really like being an adolescent at all.

You might think of Hollywood as this full-on glamorous thing and to us it was like, 'All right, mom's got an audition. Do you want to sit in traffic for 50 minutes and go in with her?'

All the albums that I grew up listening to were produced by one person.

I felt really lucky in that I've gotten to know some of my favorite artists; I get to tell them how important they are to me. But that doesn't always make me want to work with people. I feel like if I'm going to work with somebody, it's because I feel like I actually have something to add to them.

Well, I mean there are so many producers that inspire me. I used to try to imitate production by certain people. And now I'm only interested in doing the opposite of that. I'm only interested in doing production that like no one's ever done before.

I feel like the thing that I've learned a lot is when you're involved in something, you don't always get to appreciate it for what it is as much. You're focused on the details and how you can make it better. It's kind of torture.

We wrote and recorded the 'Bond' song on a tour bus in Texas.

You know, that's kind of always been our philosophy: not letting the place that we are get in the way of making great music.

To me, as a producer, I always want something to set stuff apart.

My dreams as a kid were so far below the Grammys, like, maybe selling out a show, or, like, seeing your album on a shelf in an Urban Outfitters... and the Grammys are so far above that. It's very ridiculous.

People were like, 'he's collaborating with Taylor Swift' and I was like, 'I am?' I think she's wonderful. Her songwriting has inspired me for years.

I usually don't like to annoy people in asking to work with them.

If you need to record live instruments, especially drums, it's still best to do it in a studio.

I feel like you're able to be your most creative in private environments, and not a studio where an A&R person is coming in, telling us a song isn't a smash.

I remember, one time, my dad took me and Billie to a fair. I was probably 7 years old, Billie must have been 3, and she put footie pyjamas on and then put a second pair of underwear on over the pyjamas. I remember being like, 'What is Billie wearing?!' and my dad was like, 'She's happy with it. Let's go!'

You go to a truck stop and there are key chains with names on them, and there's no Finneas. There's no Billie. They're little things, but as a kid, you just feel weirdly ostracized.

Well, predominately, if I'm writing for another artist, I'm sitting there with them and we're writing it together.

I feel like a lot of music producers have, like, the same toolbox. And I think, like, to me, as a producer, like, I want something to set my stuff apart.

I love Griffith Park.

I think it's really easy to be the altruistic hero of your own narrative and story.

I think in modern communication studies, we put a lot of emphasis on our relationships and our family relationships. Our relationships with our parents, and our siblings. I felt that there was this gap in content about communication with people who are super close to you in your peer group.

I had a very positive, wonderful, happy upbringing, and still, for several reasons, I really didn't enjoy being a child very much. I felt that I had no control over my life and everything seemed scarier and larger than life.

The first time I ever heard Airborne Toxic Event, my friend was turning 11 or something. And he had a paintball birthday party where him and me and two of our other friends went out to these paintball courses and I got obliterated. I don't think I got one hit.

The music that I listened to when I was growing up was the most important to me forever.

The worst pain in the world is shame. I spend a lot of time trying to not do anything bad to anyone, but you can't live your life and not hurt people.

For me, the best times are always going to be the most intense, the ones with the highest highs and the lowest lows.

I never thought I'd be in a position where people would be talking about my sexuality and saying how good I look in underwear.

My whole life, people have been saying, Why are you so angry?

I can bake. I made myself some nice French fries once. But otherwise I just eat out. Lots of salad bars.
