This year’s Prototype Festival includes a mix of new opera and music theatre works, several of which explore themes of origin and identity, and A Tempo this week checks in on the festival. Host Rachel Katz will speak with co-founding directors and curators Beth Morrison and Kristin Marting, as well as with Illia Razumeiko, co-creator of the work Chornobyldorf, one of the works that will be presented in-person.
