Yes, I know it will be tough for me on Judgment Day, but I have to confess a very modest appetite for Christmas-related, or just plain holiday-related, concerts. I can happily go several years between hearing Handel's "Messiah," for instance, even though I do admire the work.
This confession is by way of explaining the paucity of reports on seasonal performances around town. I do hope you've been attending them and cheering them all heartily.
Having gotten the disclosure out of the way, let me hasten to add that I have not avoided all exposure this year to events with a holiday hook. I took in two recent concerts that, while widely different in some ways, proved very much alike in others.
