Countertenor Anthony Roth Costanzo

Costanzo is a countertenor, meaning he sings in a high range that's associated with women's voices. He knows all about the history of countertenors and their predecessors, castrati. He's about to star in the Metropolitan Opera's production of 'Akhnaten,' by Philip Glass. Costanzo plays the titular Pharaoh, who many people now think was gender fluid.
