What a pity that Richard Wagner didn’t live to hear Hansel and Gretel. Every page of Engelbert Humperdinck’s fairy tale reveals how Humperdinck idolized the old master, who in turn thought well enough of his young acolyte to let him patch in some extra bars for a scene change in the sacrosanct Parsifal. Oh, well. Two of the earliest endorsements of Hansel and Gretel came from star maestros headed for immortality as composers in their own right: none other than Richard Strauss presided over the premiere, followed by Gustav Mahler, who led the second production. To this day, Hansel and Gretel’s stock among professionals remains sky-high. Just ask Patrick Summers, artistic and music director of the Houston Grand Opera, who calls the score, “without hyperbole, one of the two or three most ravishingly beautiful in the history of music.” The way he conducts his company’s ebullient new virtual production, he’ll persuade you it’s true.

An adventure begins. Sun-Ly Pierce’s Hansel, left, and Raven McMillon’s Gretel alone in the forest.

The storytelling is tops, too. Directed with up-to-the-minute TikTok flair by Lileana Blaine-Cruz, the film showcases a diverse ensemble of artists in training at the Houston Grand Opera Studio, and what scene-stealers they already are! Bouncy in overalls, Sun-Ly Pierce’s Hansel and Raven McMillon’s Gretel light up the computer monitor with histrionic zest. It’s quite a coming-out party for McMillon, whose sense of fun, voluptuous tone, and joy in singing landed her in the winners’ circle at the Metropolitan Opera National Council Auditions last month. Richard Trey Smagur, who emerged from the same studio to claim the same prize four years ago is on hand as the cross-dressing mega-Witch with the Dixie drawl.
