The Signature Theater is only going to unveil and move into its new home on 42nd Street next week, but it has already received one unusually generous housewarming gift: on Thursday the Pershing Square Foundation announced that it is donating $25 million to Signature, much of it to be used in a 20-year initiative to keep ticket prices affordable.

“This is a game-changer for us, something hugely important to our long-term sustainability,” said James Houghton, Signature’s founding artistic director. “We’ve made this dynamic new center, the first theater arts complex of this size in decades, but this ticket initiative is critical in that it provides access for everyone.”
