To repeat the same beat for twenty minutes right in the middle of a massive orchestra is to walk on the edge of madness. In this film directed by Patrice Leconte, the orchestra’s unseen hero continues to wave his baton as Ravel’s *Boléro* plays. As his mind wrestles with the darkest anxieties, he has but one task: never to lose the beat. In this scene where comedy and music intertwine, we focus on the inner world of the man behind the instrument. Despite the storms raging behind the music stand, he must resist the flow of time.
