Casady (Coco) in 2003. Sierra and Bianca Casady are North American half-Cherokee sisters. Sierra, the older of the two, was born in Iowa, and Bianca was born in Hawaii. Their mother nicknamed them Rosie and Coco, respectively, from which their musical act takes its name. In 2003, Bianca was growing restless and decided it was time for a change. Leaving her apartment in Brooklyn to travel the world, she ended up at Sierra’s apartment in Paris. Over the course of the next two months, the women spent nearly every waking hour in Sierra’s bathroom, chosen as the most acoustic and isolated room in the apartment. Soon, they had completed both a hip-hop recording (never released) called “word to the crow” and their proper debut album La Maison de Mon Rêve. Originally, La Maison de Mon Rêve was only intended to be distributed within a close circle of friends. However, by 2004 the lo-fi album had been released on independent label Touch and Go Records, who had obtained a copy of the CD and had uncharacteristically pursued signing the artists. Since the creation of their first album, the Casady sisters have been virtually inseparable.
