Henriette Motzfeldt and Catharina Stoltenberg bring the innovative spirit of their adopted Copenhagen to bear on their past, one that’s marked by adolescent choir practices and dance rehearsals in their native Oslo, winter vacations spent in small cabins nestled in the vast, untouched landscapes of the Norwegian countryside, and an innate belief in collective responsibility. Believer melds sonic touchstones from their youth, like musicals and classical music, with swirling, trance-indebted synth lines and hip-hop plus R&B vocals. Lyrically, it paints their personal conversations onto a much broader canvas. This is an 18+ event.
