Bobbie Allen has had quite the year. After releasing a few buzz-worthy singles in the past year and singing on tour with Odesza, the DC-based musician (who goes by the stage name Young Summer) recently brought her talents back to a packed U Street Music Hall. Though there’s a profusion of strong synth-pop talent coming out of the woodwork these days, Young Summer proved on Friday night that her smooth and subdued vocals combined with an expansive electronic sound are what has helped her gain recognition and continue to stand out from the pack.
