May I add that I was listening to a DG recording of Swan Lake with Seiji Ozawa and the Boston Symphoy Orchestra done in 1979.
What struck me was the amazing quality sound that puts the newer digital recording to shame. It had a rich full blooded sound with great depth in the soundstage. But recording is an artform just like performing.
In fact it was so good that I am going to get the same orchestra and conductors recording of Prokofiev R and J even though I have a good half dozen recordings in my collection. I assume it will be done by the same engineers and at same venue.
His interpretation is much more symphonic then balletic. This is definitely not a Swan Lake to dance to (incontrast to John Lanchberry's harder driven recording)
Andre Previn recordings are also very good (again more symphonic and lyrical then rythmic) as well but they were recorded in 1973 and the sound quality is not even close to the Ozawa BSO recordings (from experience HMV and Teldec have consistenly poorer sound then the competition)
Ozawa's recording is on DG doubles and is about £14
