Made up of four high school friends from small-town Pennsylvania, the youthfulness of The Districts’ was on a pedestal on their first two records. Though promising, a boyish sensibility seeped through their former records. But the group has since transformed with the maturity exposed on their latest record, “Popular Manipulations,” which boasts a tighter sound and more promise than ever before. $15. 9 p.m., 21+.
