Stephen Costello has been a beloved mainstay at the Met ever since his 2007 debut. 15 years after originating Greenhorn in Jake Heggie's Moby-Dick, he triumphantly returned to the role when Moby-Dick made its Met debut in March. He generously spoke with me in between performances about Moby-Dick, how the trumpet influenced his singing, and what opera shares with Cirque du Soleil. Enjoy!
