‘Klang’ (Friday and Saturday) It’s going to take an entire day and all three of the Metropolitan Museum’s buildings to perform Karlheinz Stockhausen’s visionary acoustic and electronic work titled “Klang” (“sound” in German). The composer had hoped to write an enveloping piece in 24 parts, one for each hour of the day. But he died in 2007 having finished only 21. For this American premiere, the Met presents the various pieces over two days, with repetitions, at the main museum on Fifth Avenue, the Cloisters in Washington Heights and the new Met Breuer Building on Madison Avenue. (Check the website for specific times and locations.) Friday at 5 p.m. through Saturday at 8:30 p.m.; 212-535-7710, metmuseum.org. (Anthony Tommasini)

Roomful of Teeth (Thursday and next Friday) This trailblazing vocal ensemble brings its distinctive blend of vocal traditions from around the world and fresh contemporary art music to an elegant fin-de-siècle interior with a program that includes Elliot Cole’s “Hanuman’s Leap,” based on an old Indian epic. At 7:30 p.m., Board of Officers Room, Park Avenue Armory, 643 Park Avenue, at 67th Street, 212-933-5812, armoryonpark.org. (da Fonseca-Wollheim)
