Fans of the musical Once will recognize its stars, Glen Hansard and Marketa Irglova, in this enormously charming Tiny Desk Concert straight from NPR Music, in which they showed off six new songs before finishing up with "When Your Mind's Made Up." It's impossible to convey how lovely — how warm and genuine — this performance was in person, but seeing the video, which really does show them sitting behind Bob Boilen's real desk surrounded by Bob Boilen's real stuff, is really stunning.
