Copysists or (99% of Concert Pianists) concertize the past obsessively.
Aside from performance being a reasonable artistic choice (even if don't personally share it, and do like composing) - can you even name 100 concert pianists, and have reasonable proof that they don't compose music privately?
I'm somewhat picky I guess...The Asian boy playing the atonal sonata...that music is always a bit mysterious and interesting.
There are tons of composers who go unnoticed usually...Alexander Tanev (Bulgaria) for example. Somewhat recently gone from this world, has composed a lot for the piano... Following are his sonata and sonatina:Sonata
Where can I get the sheet music for this?? I'm liking it a lot, I'll continue listening to the rest you posted.
