Sub-Pop recording artist Frankie Cosmos is led by prolific New York songwriter Greta Kline, whose cherubic voice and alternately goofy and witty lyrics ,whether singing odes to her departed dog JoJo, or lines like: “I wasn’t built for this world/I had sex once, now I’m dead,” will charm their way into your heart. Detroit’s Stef Chura (Saddle Creek records) and Kansas City’s Shy Boys open. Doors at 7 p.m. show at 8 p.m. $15. capitalalehouse.com.
