It was notoriously difficult to lure Michelangeli either on to the concert platform or into the recording studio. In the vinyl era those anxious to collect anything they could of the work of this phenomenon of the modern keyboard made do largely with discs of questionable origins, some of which sounded as if they had been recorded down the telephone but others of which were surprisingly good. The cd era is just a little better, and the Michelangeli-collector waits like patience on her monument to see what may turn up. I had not long ago acquired a version of Mozart's K488 by M with Giulini from 1951 and reconciled myself to the abysmal recorded quality, and now here is another version that is far better.
