As he said in his Don Giovanni:
"Those who have tasted the food of heaven
do not eat mortal viands.
Other, weightier concerns,
another aim has brought me hither!"
Thus spoke Wolfgang Amadeus Mozart in his greatest (well be the greatest written) opera with his music; -Oh and what music, music that only those in heaven can help to make, sounds that will not be heard by the unclean or ignorant. Sounds that can only be reproduced accurately with the care and skill, by one with a conscious integrity, that can reach to a decent proximity the miracle, the music. And a warning- don't expect today's or any recent generation's work to be worth anything but garbage. For proper Mozart (or far closer than today's trash) look for recordings by conductors of the first half of the century or near the half. In that generation, you will find conductors that were true to their calling, as well with uncommon talent. And you will definitely not see any of the plastic, insubstantial, worthless and shameless garbage produced these days by pompous, ignorant asses that call themselves conductors or modern artists that are so impertinent as to attempt to play music written by people with a conscious integrity.
This is what you should know about recordings these days - for I too was once listening to only that artificial trash.
Some of those old artists: Bruno Walter, Josef Krips, Thomas Beecham, Otto Klemperer, Ferenc Fricsay, Josef Hofmann, Clara Haskil, Dinu Lipatti, Jascha Heifitz, David Oistrach, and quite a few others that have long been dead.
