Carl Dreyer's 1928 silent film, "The Passion of Joan of Arc," is a great modernist masterpiece, remarkably advanced in directions that foreshadow Ingmar Bergman, among others.. At the Chan Centre on July 22, it was accompanied by the music of an oratorio called "Voices of Light," by American Composer Richard Einhorn. This calls for a large chorus, four soloists, a second group of four women soloists and a chamber orchestra. While the performance by a Massachusetts-based group called the Berkshire Choral Society, the Vancouver-based National Broadcast Orchestra, the female vocal quartet Anonymous 4, and four excellent soloists (SATB) was very fine, the music disappointed. No doubt some may enjoy it, but I found it a trite combination of Philip Glass and Carl Orff, which are already tiresome enough, in my view. Just background music, which is all right for a film, but which may as well be recorded and put on a sound track, sparing all the expense,
