Query: Great sound quality, but rushed and mechanical

The sound quality of this is just superb. However, it sounds like it was recorded by a computer with hardly any tempo variation, nuance, or pausing; just an exact metronome beat. And that beat is Roadrunner-fast. If you're impressed that it all fit on one CD, the reason is that it is played unusually fast. If you think people who don't like it that fast were all born in the '40s - well I was born in the '70s and my favorite music is rock, R&B; and jazz. But I also love classical music. This rendition is "lively" but robotic. True, you can't really go too far wrong with great music, and the Nutcracker is great, but I prefer a more organic, emotive performance which sounds like it's played by human beings.I have been listening to several recordings of Tchaikovsky's complete ballets recently, and by FAR the best one isTchaikovsky: The 3 Ballets. It blows all the other recordings away!
