This annual event is free; listeners are invited to come and go as they please throughout the afternoon to hear some of the most glorious music ever composed for the pipe organ by the musical genius and organ virtuoso Johann Sebastian Bach. Six Vermont organists: Evan Allan, Peter Berton, Lynnette Combs, Lubbert Gnodde, Karen Miller, and Carl Schwartz begin at 1:30. Donations benefit the Governor's Institutes on the Arts.
