Frost Children is an American pop duo from St. Louis, Missouri,[1] now residing near Ridgewood in New York City.

[14][15] Following this, they released their second full-length album Speed Run on April 14 of the same year, featuring artists EXUM, May Rio, 8485, and Frost Children's manager Blaketheman1000.

"[1][6] Speed Run was followed by a more analog-sounding companion project, Hearth Room, which Lulu described as an "ego-death-lifestyle-moved-upstate" album, released November 17, 2023 following its singles "Lethal" and "Stare At The Sun".

[1][18][19] Pitchfork described that Hearth Room's songs had a "gentler and sweeter sound" and followed "more conventional pop structures", comparing it to the work of Modest Mouse and Alex G.[20] One catalyst for the album's sound was a head injury suffered by Angel at a club on Irving Avenue, as she only wanted to hear and make “lush, acoustic” music while recovering.

[5] In childhood, the pair became interested in emo music through watching YouTube on their father's desktop computer, including the bands The Fray and Say Anything.

[1] Later in life, Angel's influences included bedroom pop acts Alex G and Horse Jumper of Love.

"[6] The Face described the band's audience during their 2024 tour, writing that "kids with furry tails, SpongeBob merch and Pokémon backpacks rave[d] besides silver-haired indie rockers in weather-appropriate beanies and down jackets.
