It’s well-pieced together melodic rock that gradually climbs before riding the musical momentum down a sharp decline in stampeding fashion. The quartet of Posers, opening as part of the NOFX sold-out show at the TLA, smacks with a sense of immediacy, balancing harmonious anthem-tuned choruses with a quick-bursting instrumental cohesion, wielding itself with sticky, memorable narratives. The band embraces the freeing unity of power-pop, while exhibiting a well-honed sense of firing on all cylinders exemplified in tasty guitar solos and a backend that won’t sit still. Tonight, they’ll be joined by Milwaukee pop-punks Direct Hit!, who will likely be showcasing songs from their forthcoming new album Wasted Mind, and the heavy-ska combination of Mephiskapheles lays down the path to NOFX.
