The Tufts Opera Ensemble, directed by Carol Mastrodomenico and Thomas Stumpf, presents Engelbert Humperdinck’s delightfully tuneful and beloved fairy tale opera “Hansel and Gretel.” The two performances on April 28 and 29 are fully staged and double cast, and will be sung in English translation. Free; no tickets required. Due to COVID regulations, live audience attendees at Tufts Music events must present a Tufts ID or a COVID vaccination card showing that they have been vaccinated and boosted. For others, this event will be live streamed through Tufts Music Live Streaming.
