TPDVD145 - Testimony : The Story of Shostakovich. Testimony is one of those comparatively rare events nowadays - a real piece of cinema. Palmer's prowess as an editor, his knack of juxtaposing image and music. Most importantly for a movie about a composer, there is always the feeling that Palmer understands the music. For a start he puts to rest the hoary old cliché that the private Shostakovich is only to be found in his chamber music - try listening to the 7th, 8th, 9th and 14th Symphonies.
