Cd 5: Scenes Historique, Rakastav, Romance in C, Symphony No.6
I think Ashkenazy is in his element if he plays Chopin. I haven't heard a lot but i enjoyed what i heard. But i also prefer many others.
I am no expert myself. Very few are. Probably people that knew the man himself or studied the man and his scores understand what Sibelius's music is about.
Conductors conducting their on work deliver most pure interpretations !!!
But loving music in a personal way is also important indeed. You are right.
