Performances of Trump Lear, by David Carl, have been extended through Feb. 10 at Under St. Marks (94 St. Marks Place between First Avenue and Avenue A). Directed by Michole Biancosino and co-created by Carl and Biancosino, the show opened in July. In the piece, an actor named Carl David is being held without bail for performing his Trump-inspired version of Shakespeare’s King Lear. He is forced to perform his King Lear to an unseen online audience of one, as the President restlessly watches remotely from a live feed. Performances are Saturdays at 2 p.m. Tickets ($20) may be purchased in advance at www.horseTRADE.info. Visit www.trumplear.com for more information on the production.
