As Speedy Ortiz prep their debut album, the western Massachusetts band boasts an eye-catching noise-pop pedigree: the SPIN CMJ 2012 mixtape selectees will be opening for Marnie Stern and Talk Normal on April 11 at the Music Hall of Williamsburg in Brooklyn. Additionally, the foursome worked with Justin Pizzoferrato (whose recent credits include recording the latest album from Chelsea Light Moving and Dinosaur Jr.) to re-record the first two songs they ever wrote. Those tracks, “Ka-Prow!” and “Hexxy,” will come out as a 7-inch on April 30 via Inflated Records. And with a sound as striking as its lineage, “Ka-Prow!” moves from off-kilter interplay and coolly intoned vocals to furious, foul-mouthed raucousness. You can listen to it exclusively below.
