Philly five-piece Free Energy is self-releasing its second full-length, Love Sign, on January 15, and today gave us yet another taste of the record with the song “Hangin’,” which premiered this morning at Rolling Stone. This one plays like the sequel to “Bang Pop,” the big hit from their debut full-length; the beat, guitar licks and general vibe are total parallels, though this time we get the bonus of lively group shouts, vocal harmonies and a key modulation towards the end. But enough music nerdery – rock to “Hangin'” here.
