Frost Children, consisting of siblings Angel and Lulu Prost from St. Louis, grew up in a home filled with dance music. As teenagers, they immersed themselves in the golden age of EDM, fascinated by YouTube deep dives into artists like Skrillex, Zedd, and Krewella, attended a Virtual Riot performance near them, and explored their older brother’s dubstep collection. This youthful fascination forms the basis of their third album SISTER, released on September 12 through True Panther/Dirty Hit. The album reflects themes of codependence, change, and the intensity of being together, showcasing their creative collaboration as band members, housemates, and like-minded spirits exhibiting what Angel describes as 'twin telepathy.' Support is provided by Saska.
