Some bands never change. No matter how hard they try they just can't escape the comfort of Ludditism. But others perpetually evolve - to the extent they've become practically unrecognisable to their most ardent fans. Animal Collective are one of those bands and new single Peacebone finds the New York avant-gardes sailing further adrift from Spirit Their Gone's exhilarating sonic discord. The Atari-fied synth bubbles and pulse-beat percussion still oscillate menacingly, but now an unrestrained mesh of ebullient melody thrives proudly in the foreground with newly-decipherable, off-kilter vocals. It's majestic, it's bizarre and, for those reasons, it's unmistakably Animal Collective. [Billy Hamilton]
