Arrah and the Ferns bring their countrified indie pop-rock to West Philly’s cozy Studio 34 as part of tonight’s Folkadelphia-presented showcase. Led by Muncie, Indiana transplant Arrah Fisher’s charmingly sweet vocals, the band should have plenty of new material to share after recently locking themselves away in a cabin in the woods to record their long-awaited new album that I hope to see the light of day sooner than later. They’ll be supporting prolific New England singer-songwriter Jason Anderson along with Leigh Jones and John Craigie. Studio 34, 4522 Baltimore Ave., 8pm, $10, All Ages – H.M. Kauffman
