In the 1930s, Hitler's Third Reich labeled the music of Viktor Ullmann entartete -- or "degenerate" -- just as it did with works by other composers of Jewish origin. Ullmann's music wouldn't have to be any good for us to curse the Nazis for this plain evil. Yet his music is brilliant: Check the first piano sonata here, from 1936, which moves nimbly from a funereal tribute to Mahler and onto some high-spirited fireworks. Ullmann completed six more sonatas before his later murder at Auschwitz. Jeanne Golan's playing does them justice on multiple levels here.
