Wherefore art thou…socialite? Yes, add to the list of things that make you love New York (or cringe over the fact that you live here) an Upper East Side adaptation of Romeo & Juliet. The Capulets, nouveau riche; the Montagues, old money. Can you feel the drama?! Despite this modern frame, Theater Breaking Through Barriers, which is producing the show, promises that its fresh take on the Elizabethan classic will stay “rigidly faithful to Shakespeare’s rules and form.” Previews begin March 5 at The Kirk at Theatre Row.
