Oldermost, performing tonight at Johnny Brenda’s, have that classic Americana sound. Built on earnest vocals and melodies that exude warmth, overlaid with a scarred, melancholy exterior, this band calls to mind a horse that trots at a steady comfortable pace, the finger-picked guitar gradually gathering speed circling about, the bass gaining ground and the percussion holding steady. When its soul-warming momentum finally reaches a tipping point, that horse, seeing its opportunity, makes a mad dash toward the finish line. They’re joined by Fenster, the Great American Canyon Band and Mock Suns, a bill that will run the gamut from pastoral to bizarrely adventurous. Johnny Brenda’s, 1201 N. Frankford Ave., 9pm, $10, 21+ – Michael Colavita
