Not everyone in Arcade Fire approves of their mutation into a risk-taking version of U2. Or so it would appear, judging by the debut album from Will Butler, frontman Win’s lively brother. Policy is twitchy and endearingly ramshackle, channelling the can-do spirit of early-80s indie and the affability of Jonathan Richman. It’s not all in the same vein – Anna is Talking Heads-style pop, Sing to Me a ballad – but every song is blessed with Butler’s childlike dynamism. Butler recently wrote a song a day for a week based on Guardian stories – he is very much his own man.
