This is horrible Bach (or any) playing. Insanely fast, jerky, unmusical/unrhythmic, profoundly ugly, and ultimately unexciting. Those who like it are not, I suggest, really listening to what Newman does, what the sense is, the shape, the organization, the structure, the phrasing, the hands ensemble (or unensemble).
Imagine trying to put a metronome to it. It is not "free" or "liberated" or anything else but smeary and way way too fast. Irregular, jerky, lurched, inept.
Virgil Fox was better than this. Newman was quite as he is here 30+ years ago; amazing he has had a career and recording contracts and academic appointments.
Listen to the clips on this site and see if you can follow it, or if it builds any cumulative power for you. Then find and listen to Anton Heiller play the same pieces (esp S.548 in e), or even Walcha, Rogg, Rubsam, Koopman, or Hurford.
