Among Mozart's choral works, there are three masses that are masterpieces beyond question -- even though two of them, the Requiem and the Great C minor, were left unfinished. We'll hear the other one, the Coronation Mass in C major this week.
Then it's music of Beethoven: The Choral Fantasy, the capstone of one of history's great performance disasters (hint -- it wasn't the fault of the music), and a couple of piano works by Schubert.
