Gerardo Constantini does not recommend any recording of Celibidache...

If you have never listened to a C.  recording or a live C.  performance and
never will do it, why do you write this "pamflet"? I think it is extremely
silly to give an opinion on interpretations you have never heard, on
record, tape or live.  And then comes Glenn Gould out of the hat: Gerardo
says that he made people listen to his playing.  That is true, but did
Celibidache not make listen people to his music making? Perhaps Gerardo
does not listen, but others will...  Best regards.
