Lonny Price (Merrily We Roll Along, A Class Act, The History Boys) and Matt Cowart will co-direct the musical that will run through Oct. 16. Price co-authored the book with Kitt Lavoie. Kiki Baby has a score by Grant Sturiale.

Here's how the authors bill Kiki Baby: "Germany. 1931. Christine Maladin is the only thing standing between her family and the pit of a worldwide depression, until one day a visiting impresario hears the voice of an angel floating from her flat – and determines to make her four-year-old daughter an international star. A tale of fame, fortune, failed opera divas, dwarfs, sweatshop bosses, monumentally bad parenting, and what happens to a little girl when no one will tell her 'no.'"

Josh Rhodes (Company with the NY Philharmonic, Sondheim: The Birthday Concert) will choreograph Kiki Baby, which will have musical direction by Mark Hartman. Orchestrations are by Tony Award winner Michael Starobin (Sunday in the Park…, Next to Normal) and vocal arrangements are by Annmarie Milazzo (Spring Awakening). The production will have costume design by Wade Laboisonniere, scenic design by James Noone, lighting design by Marc Janowitz and sound design by David Gotwald.
