Their sweet but frequently unsettling, kaleidoscopic vision – equal parts avant-pop, opera, leftfield hip hop and psych-folk – has managed to get up a few noses in its time, but sibling duo Sierra and Bianca Casady were never going to play it straight. Their third LP (produced by Björk’s studio magician Valgeir Sigurøsson) is recognisably CocoRosie, but throws their fractured and fragile, yet almost feral, songs into sharper relief. There’s less self-conscious muzziness and ethereal mist, more muscle. But happily, no less mystery.
