CocoRosie is the potently poetic music-based project of American cross-disciplinary performance artists Sierra and Bianca Casady. They sing eye-opening accounts of unsayable things, yet their music ultimately celebrates a spiritual freedom attainable in the purely natural world. Their songs blend a myriad of styles and references, from hip-hop and reggae through to folk and opera, shaping the most painful of experiences into memorable and evocative pop songs. Taken as a whole, CocoRosie’s music is an ongoing psychologically intimate dialogue between the siblings. Each sister has her own persona and vocal delivery; Bianca delivers hard-hitting truths in a childlike voice whilst Sierra responds in pure open tones, playing a range of instruments including the harp, flute, piano, and guitar.
