World premiere: Kimmel Center for the Performing Arts, Philadelphia, March 2022 (concert version, performed by The Philadelphia Orchestra); Metropolitan Opera House, New York, November 2022 (staged production) A compelling new opera about three women in different times and places, The Hours is based on the Pulitzer Prize–winning novel by Michael Cunningham and the Academy Award–winning film adaptation that followed. Both the book and the film make heavy reference to an earlier novel, Virginia Woolf’s 1925 Mrs. Dalloway, which forms a sort of parallel background narrative, and the opera uses Woolf’s and Cunningham’s magisterial prose as a departure point from which to explore ambiguities and fluidities that cry out for musical expression.
