That was quite possibly the worst, slowest, most painful playing I have ever heard.
Choice of tempo is not something for which one necessarily can provide a satisfactory explanation.I appreciate you taking the time to listen and also for having provided a critique of the interpretation.
Come on perfect_pitch, that is stretching things a little The worst playing ever is to be found here:
It is nice to see you here breemer and not only at P.W.!
The explanation of the choice of tempo is that it was innate and instinctive.
Well, whatever it was - it was wrong. You need to seriously consult a teacher/tutor and really get some proper training at the piano. Playing like that in a recital is just shockingly bad. Don't be one of those people who completely desecrate classical music. Keep it at the highest levels possible...
In regard to the interpretations, I don't personally feel there is anything amiss with a romantic approach to Bach's music when it is played on a piano rather than on a harpsichord, clavichord or organ, which seems to be the issue at contention here.
My question is basically why post a 12 year old video of something you hadn't practiced in 8 years?
(And yes, I feel it is also weird posting a 12-year old video. My opinion is that you are basically trying to fish for YouTube views...)
I suspect this goes well beyond what, for example, Busoni might have done. I would be more comfortable if you had presented it as 'paraphrase on' but, while I certainly don't agree with what you've done, I retain an open mind as to where it lies between the endpoints of 'interestingly eccentric' and 'wilfully controversial'.
