I had an Off-Broadway musical of my own, "Tink!," in 2016. I have a current musical, "The Cabinet of Doctor Caligari," that WAS projecting to Off-Broadway this summer, but has pushed back to a likely regional premiere in 2026 due to funding. (Side note- producers, DM me if you want to hear the demo!)
It's tough out here for new musicals. It's DOUBLE tough if you're an indie new musical that wasn't developed by IP owners or workshopped in one of the major artist incubators of New York. I've been very lucky to be based in Pittsburgh, where new major shows like "Twenty-Sided Tavern" still launch with some regularity. Pittsburgh is MUCH cheaper to work and develop in, due in no small part to the unique rules for Actor's Equity that apply to the state blending Equity, non-union professional and community together. The first workshop of my show was extremely DIY: a fully staged book-in-hand concert version of my show with a cast of ten notable local pro actors plus two musicians. The total cost? Four hundred dollars. The second staged workshop cost about three thousand, a heftier price but still literal crumbs compared to the cost of a seated table read in NYC.
Every few years, there's an ebb and flow of "out of town tryouts" coming in and out of vogue. While I understand that NYC is the room where it happens, the only place where musical theatre has major commercial legitimacy, we are living in the economy we are living in. Premiere the work out of town, at the place you can afford; you'll be glad you did.
