A classical version is assessted by me by criteria as: technique (dynamique), are the intentions of the composer transferred as accurate and natural as possible ?
I am pretty much a purist but . . . sometimes i hear such a natural fluidity in the playing of an artist/artists without changing the intentions of the composer to much that it is forgivable for me.
'Gould' seems to be a hit or a miss for me.
P.S. still learning.
Listening to classical music grows, needs training.
Right about that.
