I just watched The History of Future Folk on Netflix this morning, and I absolutely loved it. It's based around the backstory for the sci-fi themed folk music duo, Future Folk, made up of General Trius and The Mighty Kevin, who came from the planet Hondo and fell in love with our music. It's a pretty simple movie, it obviously had a very tiny budget, but it's got a good story, with fun music, and some pretty good performances from it's cast.
