Today, December 16, is an important date in any music school: the birthday of Ludwig van Beethoven (his 243rd, to be exact). Beethoven’s music has always occupied a central place at Eastman; to celebrate the great day, here is a video about the 2012 Eastman Rochester Chorus performance of one of Beethoven’s greatest works, the Missa Solemnis, under WIlliam Weinert.
