When the Metropolitan Opera reopens Monday after an 18-month closure caused by the pandemic, it will do so with Fire Shut Up In My Bones, the first opera in the Met’s 138-year history written by a Black composer. An already renowned jazz trumpeter and composer, with his adaptation of New York Times columnist Charles Blow’s memoir by the same name Terence Blanchard will bring to the stage what he describes as a universal story spoken in “our language”—the language and sound of Black America, featuring an all-Black cast. Blanchard, it seems, has managed to capture at least some sounds that for the nation’s still overwhelmingly white opera audiences will, almost certainly, be new: The particular musical quality of the 20 minutes before services begin at a Black church; the multi-sensory experience—the human percussion of dancing and the stunning visuals created by complicated synchronized group movement—of a Black fraternity step show.
