If/Then is a contemporary new musical that follows two distinct storylines in the life of Elizabeth, a city planner who moves back to New York to restart her life in this city of infinite possibilities.

The original Broadway musical reunites Tom Kitt (music), Brian Yorkey (book and lyrics), and Michael Greif (director), the creative team behind the Pulitzer Prize and Tony Award-winning musical, Next to Normal. If/Then is being produced by David Stone, who produced both Wicked and Next to Normal.

The show reunites Menzel with Anthony Rapp, her original Rent co-star (the pair played Maureen and Mark, respectively). The musical also stars Tony award winner LaChanze (The Color Purple).
