Found this link from a friend. Surprised that more people haven’t linked to this yet:
An independent animation music video by Kousuke Sugimoto, who according to his Youtube channel is a self-taught animator. This is pretty good stuff in regards to that, as well as this work he posted earlier:
The music for both of these works were done by Takayuki Manabe. I hope to see more things from both him and Sugimoto to come.
