Sunday afternoon we went to an organ concert in celebration of the 25th anniversary of the Flentrop organ at Duke chapel. Quite satisfying. We heard a Bach prelude and fugue, a piece by Cesar Franck, and a new composition by the organist, David Arcus. All were performed flawlessly. Interesting thing about an organ concert in a cathedral type setting, as a couple of people noted, is that you don't get to look at the performer (or even the instrument unless you put yourself in an uncomfortable position). I found that this actually helped me listen more to the music, rather than noting the peculiarities of the performer.
