Leave it to Pedro Costa (In Vanda’s Room, Colossal Youth) to achieve a painterly beauty with the oddest of formats, black-and-white digital video; his low-contrast imagery isolates the subjects in pools of warm shadow and gives them the haunting sense of existing outside of time. The accomplished French actress Jeanne Balibar (best known for her work with Jacques Rivette and Olivier Assayas) appears here in her side career as a singer, rehearsing and performing with the avant-pop musicians who make up her backing band. More an experimental feature than a documentary, the movie depicts their creative process as a series of discrete actions, each with its own logic. The results are mesmerizing, though rarely abstract: Costa, a former rock musician himself, understands the democratic impulse behind any good band and the simple grace of hard work.
