You know you’re in for a comic treat of an opera when after an introductory serving of serious music, you’re greeted with the specter of a hapless prince being mauled by a dragon. The Magic Flute is a mash-up of genres- part fairy tale, part circus and part religious pageant flouting astronomy and ancient Egypt. Here spectacle reigns supreme. The opera is packed full of sensory overload, with treats for the eyes, ears and the mind too. Seattle Opera’s newest production of The Magic Flute just opened at McCaw Hall at the Seattle Center and will run till May 21st.
