“Sateen” is a musical now on stage at PACNYC: Perelman Performing Arts Center, presented as a live performance in Lower Manhattan. It follows a protagonist moving through New York’s night economy, where intimacy, money, and self-invention blur into one another, and the city itself becomes a kind of witness. If this engagement marks the work’s first New York run, it also places the show inside a local tradition of downtown music-theater that treats biography and labor as material. One clear strength is its attention to the systems around desire, not just the romance.
