The quality of this recording is so poor as to render the work virtually unlistenable. The chorus, brass, Barbieri and timpani suffer the worst distortion but also Callas when in full flight. This is very sad as undernesth the distortion it is obvious Callas was in fine dramatic and vocal form. The recording makes the orchestra sound dead which it surely did not under Bernstein's baton. There is a tiny merit in the 'historical' value of the work but if this is the best digital remastering can do then EMI really should not have bothered. Cherubini's majestic work is completly lost in this dreadful flat reproduction and the whole is a great disappointment. Buy a recent recording not this one and enjoy the opera. You won't have the occasional glimpses of Callas's rare talent and unique interpretation of Medea but you will save yourself considerable disappointment in purchasing a totally unacceptable standard of reproduction (there is much better around from the 1950s so no idea why this is so poor).
This recording should come with a health warning attached on the jacket !
