She started out last year as a solo songwriter with an acoustic guitar, but it didn’t take Philly’s Katie Frank long to round up a band of rootsy country-rock players. The Elizabethtown native (and a therapist at an adult day center when she’s not onstage) began working with a variety of local players last spring, from Philly mainstay Jim Boggia to guitarist and producer Josh Werblun. As the band took shape, Frank dubbed them The Pheromones, and they add a rumbling, rambling Americana overdrive to her contemplative compositions. Today, the lineup consists of Jon McNally on drums, Kris Pirnat on bass and Kevin Killen on electric guitar in addition to Werblun and Frank; their tight and lively playing gives her confident vocals an opportunity to shine. This year the band wrapped up production on their debut LP Counting Your Curses, due out in August, and next Wednesday, July 17th, they take the stage at MilkBoy to open for the rather like-minded Sallie Ford & The Sound Outside.
