Uh-oh. World music from Columbia grads? Wait, wait, come back – Vampire Weekend’s sound works on many levels. The quartet of word nerds (“Oxford Comma,” “Cape Cod Kwassa Kwassa”) winds through afro-beat and dubby punk, infusing it with melody and punch without coming off like khaki-clad clones. Their most recent EP only adds to the list of this year’s uncategorizable-yet-infectious albums. Til We’re Blue or Destroy headline, and Aster opens. – Audra Schroeder
