Frost Children are brother-sister duo Angel and Lulu Prost. Dance music has always been the sound of home for them. Originally from St. Louis, the pair grew up immersed in the sophisticated catharsis of golden-age EDM. They obsessed over YouTube videos of 2010's festival staples like Zedd, Skrillex, and Krewella, binge-watched Virtual Riot headline sets at their local amphitheater, and dug through their brother's dubstep collection.
