Where falls the line that separates life from art? For Glen Hansard and Markéta Irglová, that's a trick question. The pair, real life musicians and real life partners, starred in the indie film sensation Once, playing musicians who eventually fall in love. The Swell Season predates Once but not Hansard's career with Irish rock band The Frames. From that vantage point, the music here is an acoustic, piano-and-guitar- based departure; for fans of the movie, however, this music needs no introduction. It is here that the pair's Oscar winning song, "Falling Slowly," first appeared.
