"We still got our appetite!" barks frontman Tim Harrington on Root for Ruin's opener, confirmation that age hasn't withered these New York art-punk veterans. Rather, building on 2007's belated breakthrough album Let's Stay Friends, their fifth LP bristles with self-assurance, perfectly balancing the primal and the poppy as it veers from soaring, Pixies-like crowd-pleasers ("Let's Get Out of Here") to no-wave discord ("Poltergeist"). Harrington's gauche disaffection can't quite mask the sophistication of his bandmates' guitar work.
