The New York Musical Festival officially begins today, which means that thousands of people will soon be swarming into Midtown theaters in the hope of discovering the next big musical-theater things. Since the festival began in 2004, it has been an important developmental stepping stone for musicals; prominent alums include Next to Normal, [title of show], Chaplin and The Shaggs: Philosophy of the World. Problem is, it can be hard to sort through all the options and decide what to see: This year's NYMF includes 18 full productions (each running for five or six performances), as well as readings, concerts and other events. Here's our round-up of ten shows that seem especially promising. Good luck!
