Tick, Tick…Boom! tells the story of a promising young composer, Jon (Jef Flores). Things will become different in January 1990 when he turns 30. For him, this means that he will not be “young” anymore. He’s reached his deadline. At 30, he should have had kids already like his father did. He should have had sold-out plays on Broadway! At 30, he’s still a promising composer. He’s been promising for years now and he’s afraid that he’s “starting to break the f***ing promise.” His is a sad but familiar story.
