Deepening confusion becomes a delightful experience watching this collaborative film by Daniel Jacoby and Araki Yu. The documentary observes the idiosyncratic sounds and rhythms of Ban’ei, a rare kind of draft horse race that takes place only in Obihiro, Japan. Capturing the behind-the-scenes operations of the race, the film gradually twists itself into a knot as the excited voices of the commentators merge into a frenzy of gibberish.
