Today, CocoRosie's incredible and mystical universe is known to all: the success of their first three albums, which sold over 150,000 copies, their song "Good Friday" used by Kenzo for a massive TV advertising campaign, numerous sold-out tours, etc. This fourth album, "Grey Oceans," marks a return to the CASADY sisters' roots. They remain an incredibly creative group, as exemplified by their first single "Lemonade," a true catchy refrain. BIANCA and SIERRA are indeed back, and "Grey Oceans" is their most exciting album to date.
