Arguably Larry Gottheim's most exuberant experiment in the single-shot, single-roll format (and his first with a soundtrack), HARMONICA trains the camera on a friend improvising a tune in the backseat of a moving car. Held out the window, the harmonica becomes a musical conduit for the wind, while Gottheim's film transforms before our eyes into a playful meditation on wrangling the natural elements into art. - Max Goldberg
