La Maison de Mon Rêve is deceptively innocent: enchanting and sweet yet eerie and twisted. An acoustic guitar paints melody through a haze of cryptic sounds and perversely angelic voices. A broken radio transmits a music box orchestra. Tiny field mice sing gospel. CocoRosie is Bianca and Sierra Casady. Sierra sings and plays guitar and flute. Bianca sings and does percussion (rattles things, makes things squeak, shakes a gold chain belt). They write all the music together. La Maison de Mon Rêve was written and recorded in a tiny apartment in the 18th district of Paris during the spring of 2003.
