You wrote that you admire Schiff’s style. I do also and would be tempted to characterize what I hear as, not lacking, but devoid of “STYLE”. Not sure I can put what I mean into words. Incredibly dignified playing in every positive sense of the word.
I am amazed by your choice of words...
Andras Schiff is a genius who gave to his second version of Bach well tempered klavier exactly the playing transcendent quality you describe concretely ...
I an glad someone put precise words on my impression and admiration for Schiff Bach...
This pianist matured so much, it is astounding...
