Frost Children - Sister

Angel and Lulu Prost have spent most of a decade making music that changes shape faster than most acts change jackets. Sister, released in September 2025, is the St. Louis-raised, New York-based siblings' most focused record yet, and the one where their scattered instincts finally lock onto a single idea: golden-age EDM, remembered with love and rebuilt with feeling.

Fourteen tracks move through French electro, big-room euphoria, and the emo-adjacent songwriting that has always lurked under the duo's noise. "Control" and "Falling" led the campaign, "What Is Forever For" and "Bound2U" followed, and Kim Petras turns up on "Radio" while Babymorocco appears on "Ralph Lauren." Porter Robinson produced "Don't Make Me Cry." Closer "2 Løve" stretches past five minutes and features MØ, ending the record on its widest and most generous note.

The duo call the process "twin telepathy," which is a fair description of how the album plays. Melding the songcraft of 2023's Hearth Room with the propulsion of Speed Run, Sister argues that modern dance music can be intensely personal without losing an ounce of impact.
