I play this myself from time to time (indeed, I played the whole suite just now), well enough to enjoy it but of course nowhere near performance level.

I’ve long thought of this as Bach’s “Psycho Girlfriend” gigue because the development of the chromatic theme through its logical progressions produces such bizarre twists and turns.

(Yes, ol’ Robbo had a few psycho girlfriends back in the day, so he knows what he’s talking about.  His two biggest fan bases seem to be cats and crazy people.)
