The musicians, the acoustics and the venue were all very good. My rating is based on my expectation that this “Christmas Gala Concert” would be entirely Christmas music. About 15 minutes were Christmas music, but another 50 minutes were Vivaldi’s “Four Seasons.” While the performance was generally enjoyable, despite the audience being unfamiliar with the work and clapping at the wrong time more than once, I really expected to hear Christmas music. The title of this performance needs to be revised to add the Vivaldi content. Admittedly I should have investigated the program content, but I believe the program title should be a complete description.
