I was only kidding! (about dumb ass)
Gould had a tendency to go against what seems natural. I very much admire his playing and musicianship, but sometimes he exaggerated his tempi - in both directions. And sometimes he convinced me and sometimes, not. I don't recall hearing his prelude and fugue, here. Bach, of course, had no metronome nor any indication of speed. It's pretty much up to the interpreter. Be sure YOU are convinced of the tempo. Never lose the living pulse. And create the fraseggio with all the colors of the pianoforte. And, if you have a chance, try the prelude and fugue on the harpsichord. You'll find that slower speeds are much more difficult to put across.
Post it in the audition room. I'm curious to hear your interpretation!
