When tears well up during stretches of Strauss and Hofmannsthal’s curious hybrid which you never expected to move you, something special's going on. The magic happened last night in an evening which I didn't anticipate equalling “the Carmelites experience” at Glyndebourne. But, in its very different way, it did, in terms of casting, conducting and a production (by Bruno Ravella) that wasn’t too interventionist but had some powerful ideas of its own.
