An intimate portrait of the early music specialist Ton Koopman, whose talents include conducting, playing harpsichord and organ, teaching, and research. Filmmaker Paul Hegeman follows the energetic Koopman during rehearsals and performances with the Amsterdam Baroque Orchestra & Choir, at the University of Leiden, and while traveling as a guest conductor in France and Spain. His accomplished spouse, harpsichordist Tini Mathot, who collaborates closely with Koopman in recital and as a recording producer, shares her thoughts on Koopman’s inspirational interpretation of Baroque period composers. Viol specialist and longtime friend Jordi Savall appears in performance with Koopman.
