There are deftly wielded forces of darkness and light at work on Vampire Weekend’s third record. Elegiac, alive with ideas, and coproduced by Ariel Rechtshaid, Modern Vampires of the City moves beyond the grabby, backpacking indie of its predecessors. In fact, whether through the hiccuping, distorted storm of “Diane Young” or “Unbelievers”—a sprinting guitar-pop jewel about the notion of afterlife—this is nothing less than the sound of a band making a huge but sure-footed creative leap.
