The history of rock is full of sibling collaborations: the Everly brothers, the Davies brothers, the Wilson sisters, Jack and Meg White (actually, scratch that last one). But does shared DNA guarantee anything? In the case of CocoRosie, the answer is a simple “no.” La Maison de Mon Reve was recorded in a tiny Paris apartment by the Casady sisters (Bianca and Sierra). But while these recording environs seem terribly cosmopolitan, you’ll hear it in the mix, which bears the unmistakable sheen of something that lacks any sort of real editing. While that approach may be okay for the CD you recorded one night while drunk (and still force your friends to abide), CocoRosie’s effort has been released to the public. Samples of rain showers and ringing phones coupled with lyrics like “Oh Sailor / Oh sail me / Silver mast do impale me” (“Tahiti Rain Song”) delivered with affected, Katharine Whalen (Squirrel Nut Zippers) vocal stylings, benefit no one.
