This packed bill should appeal to those who can't choose between college radio and classic rock. California's Fling adds buzzing slacker guitars to Beatles-isms, creating a concoction of strung-out distortion and hyperactive pop hooks. It's like following an espresso shot with a high-gravity beer. Black Mountain's Floating Action coat laid-back but precise lo-fi soul in a blissful haze. Bass and guitar lock into a driving groove as singer Seth Kaufman lays out charmingly neurotic narratives with a comfortably rough croon. Schooner opens. —Jordan Lawrence
