The Coral were once the Heston Blumenthals of pop: they used the same ingredients as most other indie bands, but what they concocted was refreshingly strange. But with their 2007 album Roots and Echoes, they transformed into meat-and-potato cooks of the plainest kind. Butterfly House seems to stick to the same menu of grownup, classic folk-rock: earnest opening track More Than a Lover rakes over a severed relationship; Sandhills and Two Faces have sweet harmonies but sound as derivative as the High Llamas. For all the catchy choruses, you miss the extremes: nothing here is as outlandish as Simon Diamond or as cheerfully accessible as In the Morning. Slowly, though, the album's merits emerge: its aqueous guitars, its impishness – does 1000 Years deliberately quote from the 1980s pop hit Waiting for a Star to Fall? – and its surreal undercurrent, particularly on the swirling, spooky Coney Island. Slowly but surely, the Coral are learning how to sound both mature and mercurial.
