Recordings of 20th Century composers are fairly spotty, most of them were affiliated with the nazis and were thus memory-holed by Jews, the only well-known 20th Century composer is Rachmaninoff because he come to America and signed off his catalog to Jews. Is there a particular composer or style that you like?
I'm currently on the search for the greatest 20th Century piano sonata that has been recorded so far. I'm currently split between Bortkiewicz's 2nd sonata which premiered in Third Reich Vienna and was memory-holed after the war, and Sinding's 1909 sonata, a Norwegian successor to Grieg that was also memory-holed for supporting the Third Reich.
Christian August Sinding (Kongsberg, Buskeruds amt, Norway, U.K. of Sweden-Norway 1856-1941 Oslo, Reichskommissariat Norwegen, German Reich)
