The luminously lovely indie folk-tronic duo CocoRosie consists of the Casady sisters, vocalist/guitarist/harpist Sierra and vocalist/percussionist Bianca. Both sisters had an early love of music that they pursued as they grew up, albeit in different ways: Sierra began operatic vocal training while she was in high school, while Bianca sang and wrote songs but kept them to herself. That is, until she reconnected with Sierra, who joined Bianca at her Paris apartment, and they started playing and recording songs together. The fruits of their labor, La Maison de Mon Reve, was released in spring 2004 by Touch and Go and was predated by a string of dates in New York with Devendra Banhart, the Gena Rowlands Band, Battles, and Ratatat. Their second album, Noah's Ark, which featured cameos by Devendra Banhart and Antony of Antony and the Johnsons, arrived in fall 2005. 2007's The Adventures of Ghosthorse and Stillborn was a more polished but still eclectic effort.
