Which Gould performance ? He himself changed quite a bit in his many Bach performances over time, so it's interesting to listen and contrast his earlier, younger performances with his later works. I find many of Bach's music simultaneously "robotic" (brainiac, rational, calculating, etc) and extremely emotional at the same time and for me, that's one of the main draws of his music.
