This newest characteristic from the eccentrically experimental Catalan director Portabella is a ravishing, typically faintly bonkers celebration and contemplation of the position Bach’s music performs on the earth at the moment. Mixing historic reconstruction with very loosely linked ‘dramatic’ scenes and documentary sequences, the movie constitutes a playful, painterly sequence of variations on the argument that Johann Sebastian modified the way in which the world hears due to his extraordinary ear for concord.
