Before her transformation into the lustrous blonde Austra, Toronto’s Katie Stelmanis was just a brunette with a professional choir background and a Kate Bush falsetto. Her new project is heavily vetted by glam rocker Diamond Rings and supported by Fucked Up record imprint One Big Silence; think one big GaGa/Glee crossover. The goth banger “The Beat and the Pulse,” marries a house music bounce with Stelmanis’ operatic soprano. With ArpLine and Forma.
