Coco Rosie are two American-born sisters, Sierra and Bianca, who started making music together in Paris in 2003. The nomadic duo (currently and temporarily residing in New Mexico) spent much of 2008 writing and recording in Buenos Aires, Melbourne, Berlin, New York, and Paris, finding amazing and diverse musicians to collaborate along the way. The result is their 11-song Sub Pop debut, Grey Oceans, due out May 11th, 2010.
