They’re pacing themselves. They’re not rushing the next record—they’re doing it right, and I respect The Shackeltons for that. But the new songs that Chambersburg’s favorite moody rockers have performed in concert over the past year are so fierce, so chilling, so alive, it would be criminal if we let them go unheard. Back in January, a demo of “Mum” was featured in the Philly Local Philes. Today, we have the full Key Studio Session the band recorded in early February (when it was in town for a Central Pa. showcase put on by our buds at Tri State Indie). There was a lot of warmth and good vibes filling the WXPN studio that Saturday evening; sax man Randy Bucksner sat in to lend “Call Call” an unexpected X-Ray Spex vibe, singer Mark Redding sang into a cleverly rigged telephone mic, and the band strung Christmas lights across the studio floor. A full six unreleased numbers were played, from the dramatic, mostly instrumental opener “Records” to the angelic closer “Lights.” The set The Shackeltons delivered upstairs after recording was equally powerful. Harrisburgers can catch them live opening for The Joy Formidable at the Appalachian Brewing Company on April 1; for Philly area fans, they play Berwyn United Methodist Church on April 9.
