This is a song that can be described as 'rewarding' for the flourishes of piano that build it up to a slight crescendo at the very end. At first I believed this to be a field recording from the 1940's until I did a little googling and found a myspace page. I believe this to be written by someone who loved that "O Brother Where Art Thou" soundtrack as much as I did.

Here's a video for a Timber Timbre track I found on their website; it's overly simple but it visually captures the group's grainy aesthetic perfectly.
