Opera Philadelphia presents what NPR has called "A conductor's dream come true": Verdi's "Requiem." Joining soloists Leah Crocetto (Don Carlo), Daniela Mack (Carmen), Evan LeRoy Johnson (Carmen), and In-Sung Sim are over 80 instrumentalists and 100 choristers, resulting in a dramatic exploration of the full range of human emotions experienced during the Roman Catholic mass for the dead.
