I have just downloaded and am playing a newly remastered recording in high-resolution audio of Mozart’s Piano Concerto No. 24 with Glenn Gould as soloist. It was recorded in 1962. It sounds utterly fresh and immediate, as though it were the audio equivalent of Doctor Who’s time machine.
I never heard Gould play live, but I have listened to his recordings all my life with awe and admiration. I fell in love with them as a kid via old mono LPs heard over a cheap record player in my bedroom. I listened to them all through college on various formats, including worn-down records through crummy headphones in my college music library. I had them on early, awful cassette tape. There were the harsh digital transfers of the early CD era and then the better ones.
