Was Katie Stelmanis's—aka Austra's—electropop song ever about happy lesbian love? No, but the powerful-voiced Canadian's ability to transform her heartbreak into hypnotic disco hits (like ABBA with a touch of humor) never ceases to amaze. She already gave a preview of her current work “Chin Up Buttercup” at the “Glass Danse” festival, and now Austra fans can look forward to an entire evening of new songs.
