What a difference an album makes! Adding a bass player to their original dynamic-duo lineup, Eternal Summers move beyond childlike, K-Record–inspired "dreampunk" and mature into a band that might have graced the stage with Helium, Superchunk, Blonde Redhead, or your other favorite '90s indie rock group. The production's sharp, creating a wall of sound from Nicole Yun's guitar chords. Where 2010's Silver clanged and banged like a parent-annoying garage band, Correct Behavior moves ES into the clubs. Drummer Daniel Cundiff talks out his vocals on the humorous and Sonic Youth–like "Girls in the City," but it's Yun's reverb-heavy vocals that bring about a battle between the group's shoegaze possibilities and its urban sprawl. For a band from Roanoke, Va., Eternal Summers sound like they have New York City on their mind. "Wonder," "You Kill," and "I Love You" teem with the energy of a city that never sleeps, while guitar lines rattle along like subway cars. By the slow dance of "Good as You," the relief is palpable. Every band needs a little sweetness in life.
