London may cry foul over Hamlet’s misplaced to-be-ing and not-to-be-ing but Edinburgh is in raptures over a Magic Flute which ditches its spoken dialogue entirely. Directed by Barrie Kosky and Suzanne Andrade, and first seen a couple of years ago on Kosky’s adopted home turf at the Berlin Comic Opera, the production turns Mozart and Schikaneder’s beloved singspiel into a sing-stumm, in which silent-movie captions and moon-faced gazes replace the original spiel, underscored by fortepiano improvisations with a spot of Chinese opera thrown in for good measure.
