In this post-Hamilton world, (a) all stories about Broadway must contain the word Hamilton and (b) you better be ready to innovate. Kristen Anderson-Lopez is ready to handle the latter (and probably cool with the former). The woman behind the delightful tunes of Frozen is working with three-time Tony Award–winning choreographer/director Kathleen Marshall (The Pajama Game, Anything Goes, Nice Work If You Can Get It) to bring Broadway its first-ever a capella musical, In Transit, due this fall.

A statement posted by Deadline explains the tale as

"...a new, modern musical bringing to life a vivid tapestry of characters and music in the city that never sleeps…or stands still. Inspired by the vibrant rhythms of life on the subway, In Transit follows the intertwining lives of 11 New Yorkers, all hoping to catch the express train to success, love and happiness…and the stops they make along the way.”

Anderson-Lopez co-wrote all the songs in Frozen, which grossed $1.28 billion at the worldwide box office, with her husband, Robert Lopez. They won GRAMMYs for Best Song Written for Visual Media and Best Compilation Soundtrack for Visual Media and the Oscar for Best Original Song with "Let It Go."

In Transit's book, music and lyrics with James-Allen Ford, Russ Kaplan and Sara Wordsworth. vocal arrangements are by Deke Sharon, who's got credits on Pitch Perfect and The Sing-Off on NBC, is handling vocal arrangements, which we're guessing are of extra importance for an a cappella show.
