sufjan stevens

Hi, I'm sorry I've just stumbled upon your question.
The thing is, I've discovered about Sufjan doing the soundtrack to this short film only recently.
Though it was never officially released, you can find the 11 untitled piano pieces on side 4 of the vinyl version of Sufjan's "All Delighted People EP". They are a kind of "hidden tracks" on that gorgeous EP he released in September 2010.
You can find more info (and buy the EP) on the following link :

Found the link! Someone ripped the soundtrack from his "All Delighted People" vinyl record and uploaded it as an mp3. The download link is: http://www.mediafire.com/play/sdd4dvqpg39sbuw/ADP+Side+D.MP3

It's beautiful...
