This article suggests that we DO in fact live in a world in which it is possible to listen to totally (or sufficiently) accurate DISEMBODIED performances.
The author maintains that the technology is now so perfect that you can't tell the difference between an original performance and the replay of that performance at the same piano.
I don't trust myself NOT to be distracted and, perhaps, even somewhat negatively prejudiced by facial expressions and gesticulations. Case in point: Eva Gevorgyan's performance (today) of the Chopin E Minor Concerto (the final stage of the Warsaw Chopin Competition). The E Minor (for me at least) is hard enough to listen to repeatedly without having to endure, as well, the emotional externalizations (where they exist) of the soloist. That's probably WRONG of me. I readily admit that. But I had to close my eyes to Gevorgan's gesticulations after a couple of minutes into the piano's entry in the first movement. (Even after closing my eyes it was already too late. I couldn't get the body language out of my mind; so I stopped listening altogether.) So in this instance, Gevorgan may have given a good performance, but I'll never know. My loss, presumably, because, of course, the music should come first in any performance; and a REALLY GOOD listener (or adjudicator?!!) must be prepared (arguably?) to mentally bracket unwanted facial expressions, body language, etc., etc. Other listeners, alternatively, may have thought her body language a PLUS. And that's OK, too. I just don't fall into that category. In fact, I'm starting to wonder whether her body language MADE ME THINK that the dynamics and rubato were extreme, unnecessary and even unhelpful. As I say, I don't trust myself to separate body language from the purely auditory component of musical expression. (Maybe there are two aesthetic experiences and "works of art" or "forms of musical expression": the audio only "work of art" and then something slightly (but sometimes significantly) different: the audio AND visual performance, which is a different creative act in some way.)Audio recordings have their benefits, because that question doesn't come up!
