The Swell Season are Glen Hansard (from the Irish band the Frames) and Marketa Irglova (classically trained Czech pianist and vocalist). In 2007, Once, a film about two people meeting and falling in love on the streets of Dublin, became an indie phenomenon, as audiences everywhere responded to the unassuming charm of the two leads, Glen and Marketa, and the beautiful music they made together. On the way to going gold, the Once soundtrack brought the Swell Season onto the stage of the Academy Awards, where the band won the Best Original Song award.
