Well, these two audio documents are full of questions that I turn to you, if you have any opinions or if you know anything about it.
It is quite well known that Pollini was a rather shy man and apart from Abbado, Böhm (his favorite conductors: I know he also appreciated Jochum very much), followed by Boulez, Muti and a few others, he never established large and continuous collaborations... Perhaps some of you have news about the meeting with Karajan. Very interesting document, anyway: it is a nervous and sensitive reading by Pollini (particularly in the Finale) that I have not always found in his other live/studio recordings of the Concerto.
There are also doubts about the authenticity of this Beethoven 4 by Michelangeli... Perhaps someone better informed can clarify.
