The official movie description is:
A modern day musical set on the streets of Dublin. Featuring Glen Hansard from the Irish band "The Frames," the film tells the story of a street musician and a Czech immigrant during an eventful week as they write, rehearse and record songs that reveal their unique love story.
It truly is one of the most beautiful love stories I've seen in a long time. And for those who are generally turned off by musicals, in this case the music is so perfectly integrated into the story that I don't even consider it a musical per se. I highly recommend this movie.
Now I am off to check out more music by Glen Hansard and The Frames.
