Part III in the series "Glenn Gould Plays Bach" spotlights Gould recording Bach's "Goldberg Variations" in a sound studio. In a brief introduction, he reminisces about his first recording of the pieces and explains why he wanted to record them again now, a quarter of a century later. It was to be his last recording of the "Goldberg Variations" and perhaps the last time he played the work: Glenn Gould died the year after the recording was made.
