In 1928, the centenary of Franz Schubert’s birth, H. L. Mencken began a celebratory essay with these words, “Franz Schubert… has evaded the indignity of too much popularity.” And Mencken lamented that, “Great stretches of Schubert’s music, indeed, remain almost unknown, even to musicians...” That’s in 1928. Now it’s true that much of Schubert’s music wasn’t published, or even publicly performed, until long after his death—so perhaps that helps explain things.
