This is absolutely the lowest quality of recording I have ever heard. Any music lover would do well to steer clear of this recording. It is a live recording done in 1966. You can hear people coughing in the audience and the microphone being moved around. Unfortunately this information was not available in the description of the cd, or I would not have purchased it. It is a shame that a great composer like Tchaikovsky would be blasphemed by such a poor reproduction.
