TIME100 Honoree Jack Antonoff is making his Broadway debut later this year. It was announced on April 16 that the famed music producer would be crafting the score for the modern adaptation of Romeo + Juliet, starring Rachel Zegler and Kit Connor. Antonoff tells TIME that he spoke with Florence Welch, who did the score for The Great Gatsby at the American Repository Theater in Cambridge, Massachusetts. [time-brightcove not-tgx=”true”] “She’s walking me through it,” he says, adding that Welch has given him “a lot of tips.” When asked about the specifics of the conversation, Antonoff said that “it’s private.” Tony-winning director Sam Gold, who will direct the Zegler and Connor-led Romeo + Juliet, is working with Antonoff on the sound for the new show.
