Opera Philadelphia’s Festival O featured a triumphant world premiere about Nellie Bly’s work exposing the conditions at a 19th-century asylum, as well as a production of Verdi’s convoluted love story; director Claus Guth and tenor Jonas Kaufmann staged a gripping performance of Schubert’s ‘Schwanengesang’ (‘Swan Song’) at the Park Avenue Armory in New York.
