Humphrey Burton's booklet note is informative and enlightening, and provides a unique perspective on the conductor and the DVD program - in particular the rehearsal, which he directed. As an eminent broadcaster, biographer and director, he had a 20-year association with Bernstein, during which he directed over 170 concerts and documentaries. The DVD also contains the rehearsal of the Enigma Variations at the BBC studios, and an interview with Leonard Bernstein by Barry Norman about the themes relating to the variations, with Japanese, German and French subtitles. This is the first release of this material on DVD.
