Grey Oceans is the fourth full-length studio album by CocoRosie. It was released in May 2010. It is the band's Sub Pop Records debut since their departure from Touch and Go Records. The album has a different sound to former releases. The production is clearer; the instrumentation is brighter and less electronic. It features a common use of string instruments (mandolin on Trinity's Crying, sitar on Smokey Taboo and harp on Gallows) and piano.
