Rhythm guitarists Noah Bailey and Jordan Munn share vocal duty: The former shouts through cock-rocker "Powder Keg" and seduces the bottle on "Goodnight Little Drunkard," while the latter pledges through clenched teeth on "Foreigner." Rounding out the three-guitar attack, guitarist Jon Binford lets loose with Bloodshot-loving solos in "Union Ride" and "Drunkard" while dousing radio-friendly "Like, Come On" and "Roman Admirals" in synthesizers that recall Adventures of Jet more immediately than The Cars. More D-FW music appreciation can be found in the highly Slobberbonian "Foreigner" and a dedication to Centro-matic in the lyrics to "Revival," but when the ZS isn't name-dropping, they're singing about, um, war. Political affiliations aren't apparent in the songs, but the dedications to Vietnam and the Civil War should make this EP a lock in any American-history teacher's collection. Well-sung harmony parts and a few subtly pretty songs may not stop discerning listeners from casting this aside as overdone pop-rock fare, and the EP seems more like a portfolio than a cohesive record, but these are minor gripes for a promising debut. If they keep this up, the ZS will find themselves on teenagers' walls in no time.
