Dynamics of the Subway animated video by Keita Onishi

This black and white animated short by Keita Onishi (with music by Haisuinonasa) uses the agglomeration of shapes to create a visual understanding of how the elements of a song fit together:

Each note from the instruments is represented by a geometric shape in the animation; while these shapes move in sync with the song, they also form the parts that create the subway itself.
