And it’s not just for New Yorkers. Through Nov. 3, audiences at home can encounter the menacing title character of “The Phantom of the Opera” via Theater in Quarantine’s livestreamed production. Unlike “Masquerade,” the immersive version of Andrew Lloyd Webber’s 1986 musical now running in a former art supply shop, this one is being broadcast from a 2-foot-by-4-foot-by-8-foot closet in Joshua William Gelb’s East Village apartment.
