But on their new album Overground they’ve found a new vitality and come across as almost as fresh as those 2007 singles. Adding Emily Roll from Shelley’s other band XV on saxophone might have something to do with it. The jittery “Return to Format” says it all in its title. Out on Gingko next month.
