Also in its thirteenth installment is the less conventional “Thirty Years Christmas Carol” (Ars Nova; Dec. 8-9), an annual series that began in 2013 and will continue through 2042. Every year, the same couple—played by Andrew Farmer and Ryann Weir—age in real time as they navigate the vicissitudes of life, which so far have included a pandemic, a marriage, and a baby. But regardless of what’s going on in their lives, they always make a point of reading Dickens’s story aloud together over the holidays.—Dan StahlAbout TownAmericana
