When Fort Reno announced the first hints of its summer concert lineup, we were excited to see America Hearts on the opening bill. America Hearts is a supergroup of sorts whose members have played in Gestures, Edie Sedgwick, and Medications. Plus, Olivia Mancini plays bass. In case anyone has forgotten how awesome that sounds, tonight is the night to find out, since rain bumped America Hearts’ performance to Fort Reno’s closing night. We asked singer and primary songwriter Jess Matthews a few questions in advance of tonight’s show, which will totally not be rained out — looking at the sky pleadingly — right?
