On Sunday, with about six years of musical-theater writing experience between the two of them, the Gen Z songwriting duo beat out a list of powerhouse Grammy nominees that included Andrew Lloyd Webber’s “Cinderella”; Conor McPherson’s “Girl From the North Country,” built around Bob Dylan songs; and a Stephen Schwartz musical.

Speaking on a video call from their hotel rooms in Las Vegas, where the Grammys were held, Barlow, now 23, and Bear, 20, discussed their album’s unanticipated success, their practice of collaborating creatively with fans and where their careers are headed (starting with a Broadway-bound musical that they can’t yet discuss).
