I bought two CDs of Glenn Gould playing Johann Sebastian Bach: Goldberg Variations (1981) and The Art of the Fugue. He’s a brilliant pianist and he really rocks the Johann Sebastian Bach but I sometimes wish he had shut up during the recording sessions. I don’t hear it during the organ fugues but his off-tune humming comes through on many of the piano tracks. In some places it’s cute but mostly it evokes jittery images of Frankenstein hunched over his work in one of his mad genius fits. Excellent albums.
