The Swell Season 'Fall Slowly' in Our Studio

Before Glen Hansard and Marketa Irglova took home the Oscar for Best Original Song, they stopped by the Interface to show us exactly why they've captivated audiences around the world.

Prior to starring in the critically-acclaimed indie film 'Once,' Irishman Hansard had already been creating music with Czech singer-pianist Irglova. While currently the frontman of the Frames, Hansard plans to continue focusing on the Swell Season, the band name under which he and Irglova are billed.

"I love being in a band, I love rocking out, I love going on tour with the boys -- I love everything about it," Hansard tells Spinner. "But I guess right now I'm just really enjoying the simplicity with what's happened with the film and what's happened with Marketa."

Watch the charismatic duo perform their Oscar-winning song, 'Falling Slowly,' as well as two other gems from the 'Once' soundtrack. Also, find out which actor was originally slated to play the film's lead role in the exclusive interview.
