Pulitzer Prize-winner and MacArthur fellow John Harbison has composed a Requiem for our time—a moving choral work that incorporates the composer’s distinctive sensibilities while drawing deeply on the tradition of Latin sacred music. Completed in the wake of the 9/11 attacks, Harbison’s Requiem is full of dramatic passages from singers and musicians alike, with abundant opportunities for vocal soloists, brass and percussion to shine. “I wanted my piece to have a sense of the inexorability of the passage of time,” the composer says, “for good and ill, of the commonality of love and loss.”
