Richter was the great Russian secret who's fame grew to big for Russia to contain him. Listening to this recording makes one wonder if great artists like exist today. I purchased this disc by chance a number of years ago and I have to say, if like myself, you thought you very perfectly happy with your Ashkenazy / Rachmaninov no.2, then you really are missing out on a great deal by not owning this disc. If you are in any doubt then compare the final few minutes with your favorite recording and I guarantee (just like the first reviewers piano teacher) it will move you to tears. Anything else by comparison pails into insignificance. Incidentally, the Rachmaninov dates from 1959 and the Tchaikovsky from 1963 and the sound quality on both is first class. The Tchaikovsky is adequate, but buy it for the Rachmaninov.
