Parts of my answer are worked in my topic, beginning of a piano depression, which also questions the relativity of another concertpianist playing the same works again and again.
I wrote about A. Schiff. Who started recording Beethoven when he was 50th.
It heapens by coincidence that when I was younger I saw myself flying around giving recitals all over the world.
And at the same time now It doesn't give that same feeling anymore.
My furiosity that goes beyond my own piano abilities is the fact that the classical topindustry, meaning, the top agencies with big names, with or without substence, don't care a damn about those lost and forgotten, or not forgotten, but never played great composers.
Play a concert by F. Ries and there may be people who say, hah, finally, not a Beethoven again.
Barbie Yuyu who finds Shostakovitches 2nd concert too easy, the pretentious pratt.
They have nothing to say, and still they manage to infiltrate in every aspect of the performance industry. Pierre Alain Volondat, queen Elisabeth winner, exiled to a provincial french academy. My god.
Lennie Bernstein gave children concerts, educated them with enormous success, best conductor, pianist, composer.
Now, that's what great musicianship is about.
A french book in 2 parts has been written on every piano composer, 3000 pages. Maybe 5 % of it is played today.
Well, do something and learn to know other composers to. Cpe Bach was called by Mozart "our father". Nowadays not anymore.
Remember, that a large portion of concertgoers are there for the performer, for theirr networking with champagne afterwards,...
Argerich is right. I like playing piano, but not being a pianist.
