CocoRosie is a musical group formed in 2003 by sisters Bianca "Coco" and Sierra "Rosie" Casady. The sisters were born and raised in the United States, but formed the band in Paris after meeting for the first time in years. Their music has been called "freak folk",[2] and incorporates elements of pop, blues, opera, electronica, and hip hop.

CocoRosie began as a duo, with Sierra singing, playing the guitar, piano and harp (how cool is that) , and Bianca singing and manipulating various children's toys (how creative) , electronic and percussion instruments, as well as other exotic noisemakers. They subsequently added various backing musicians, usually a bassist, keyboardist, and beatboxer. They have been a very active touring group, playing across Europe, the United States, and elsewhere. They have released four full-length albums: La maison de mon rêve (2004), Noah's Ark (2005), The Adventures of Ghosthorse and Stillborn (2007), and Grey Oceans (2010).

My Girl Katy sent this song to me today and reminded me to stay on top of what this band was doing. You should too. :)
