If there’s a red pen waiting for The Connector, perhaps it should underline the challenges of telling a tale with a twist that most of the audience will see coming from miles off. (The creative team hasn’t been shy about giving the game away in interviews either.) Indeed, you may wonder if there’s merit in an edit that, by spilling the beans earlier on, spent more time in trying to make sense of Ethan’s unraveling rather than simply hurtling toward it. Perhaps, but The Connector’s momentum is already pretty addictive, thanks to the electric collaboration of the writers and director Daisy Prince, who brought the concept to Brown shortly after helming his off-Broadway musical The Last Five Years in 2002. Prince keeps Robin and Ethan’s officemates constantly in motion and always on stage, either typing away at their desks or observing the action with intense curiosity, offering backing vocals while perched on piles of manuscripts that tower on either side of the stage. And Brown’s score, livelier if less sweeping than those for Parade and The Bridges of Madison County but more clever and compact than anything else he’s written, keeps moving too. Where he most excels as a composer, in soaring vocal lines that gaze down on nomadic grooves laced with sizzling piano licks, is the perfect landscape for a show like this. (He also conducts the show’s entire run from the keyboard.)
