Known for their mix of rave chaos and melodic sincerity, Frost Children have built a cult following in New York’s hyper-online avant-pop scene.
Originally from St Louis, siblings Angel and Lulu Prost have turned contradiction into cohesion since they started making music back in 2019. The duo started quietly building their sound before breaking out with Speed Run, their third album, in 2023.
Their latest album, Sister, released in September, captures their artistic evolution in real time. It’s their most refined project yet, sleek, emotional, and danceable without losing their signature sense of play.
We sat down with Angel and Lulu to talk about growing up in the Midwest, navigating contradiction, the myth of coolness, and why dance music should probably cap at 160 BPM.
You grew up in St. Louis and were raised in the church before forming Frost Children and moving into this hyper-online, genre-blending music world. Which values or lessons from your upbringing still anchor you as artists today?
"You should live life with rules."
Lulu, you studied music formally, and Angel studied neuroscience. Do you feel those backgrounds bleed into the way you approach making music?
Lulu: "I honestly learned nothing important about music at my music school. I had a Japanese literature class that influenced me more. It was a scam for the most part."
Angel: "Music is exactly like brain surgery."
There’s that theory that it’s harder to be cool in a small town than in a big city, do you think that tension influenced your sound?
"I think it’s actually easier to be cool in a small town because you only need to be slightly lit and you’ve already transcended everything. When you go to a big city, you realize that, and shouldn’t change anything."
You’ve previously said that part of growing up with church music taught you simplicity in melody, communal singing, and reverence in lyrics, but you now move between extremes. How do you navigate that tension between sacred intimacy and explosive expression?
"It’s all sacred, the soft moments and the big ones."
Could Frost Children have existed the same way if you stayed in St. Louis? What does New York give you that no other place could?
"New York is uncomfortable and borderline unlivable, which is why all the best art is made there."
Do you think your sound comes from holding contradictions rather than smoothing them out?
"I think we’ve played with contradictions in music in the past, but consistency is something we are interested in now."
With Sister, some have noted your sound feels more streamlined, matured. As you grow, how do you decide what to let go of, which sonic experiments, aesthetics, or old influences to move into a ‘next’ era?
"I feel like our objective as songwriters has shifted with time. Our mission these days is to make dance music that lyrically feels sound and intentional and emotional but still doesn’t take itself too seriously too. That’s why we are important to EDM in general."
The stitched-together apple from your Sister campaign feels loaded with symbolism, hybridity, tension, maybe even mutation. What does the apple represent for you?
"Beautiful companionship. #sister"
You’ve used apples in multiple visuals, why that fruit in particular?
"It’s the most emo fruit."
Is there something people assume you both are, or want you to be, that doesn’t reflect what you actually want to create? Something you feel pressured to do but resist?
"I think people tend to think we are trying to “disrupt” or “cause chaos” or something. If that happens it happens, but we are really just tryna make beautiful music you can lose yourself to and escape."
You’ve been described as part of a revival or reimagining of ‘indie sleaze,’ hyperpop, art-pop... How much do these labels help you, and how much do they constrain (or misrepresent) what you’re trying to do?
"I wouldn’t say they help or hurt us, we don’t think about it like that. I suppose these types of names happen to every movement in music. It’s not something we ever talk about."
You seem to draw from hymns, hyperpop, indie rock, electronic, folk, a lot of influences. If you could influence the broader music, fashion or culture world with one thing you believe is underrepresented now, what would it be?
"Jpop."
Where do you see EDM going next? Do you think sounds like hyperpop are a more evolved or even more tasteful future for dance music?
"Hopefully it sounds more like Frost Children."
Who would be your dream collaborators, whether from today’s scene or a past era?
"We’ve already done them all. But we won’t stop."
What’s your most unpopular opinion about music or the culture around it right now?
"Dance music should cap at 160bpm."
What is your current obsession at the moment?
Angel: "Extra dirty Martinis."
Lulu: "Old Hollywood black and white films (current one being Seconds from 1966 by John Frankenheimer)"
What would you tell young creatives trying to carve out their own lane right now?
"Be your own biggest fan and know what u do is important, surround yourself with people who do the same."
