The late string quartets of Ludwig van Beethoven, composed in 1825–26, are justly revered. Opus 132—No. 15 in A minor—is the second to last, and at its deep center is the Molto Adagio–Andante, a movement that speaks to Beethoven’s yearlong battle with grave illness and feels like the sound of thought. Opus 132 is said to have inspired T. S. Eliot’s Four Quartets. “I find it quite inexhaustible to study,” Eliot wrote. The Angel’s Share has scheduled two performances each evening, one beginning at six P.M. and the other at 7:30 P.M.; they commence with an hourlong spirits tasting, followed by a twilight walk or trolley to the cemetery catacombs, and then the hourlong performance. —Laura Jacobs
