David Stone, who also produced Wicked and Next to Normal, is shepherding the project about a woman on the cusp of 40, who returns to New York City to start fresh.
If/Then has choreography by Larry Keigwin, set design by Tony Award nominee Mark Wendland (Next to Normal, The Merchant of Venice), costume design by Emily Rebholz (Bloody, Bloody Andrew Jackson; Vanya and Sonia and Masha and Spike), lighting design by Tony Award winner Kenneth Posner (Kinky Boots, Wicked) and sound design by Tony Award winner Brian Ronan (Next To Normal, The Book of Mormon).
According to the creators, "If/Then is an original musical set at the intersection of choice and chance, where the road you takes meets the road you didn't. Tony Award winner Menzel makes her much-anticipated return to the stage in this contemporary new musical as Elizabeth, a woman rebuilding her life in New York, a city of infinite possibilities."
