You’d expect a degree of mischief and bafflement in an opera about mistaken identity, closing with a scene set at a masked ball. But Tim Albery’s new Opera North Un ballo in maschera is confusing for the wrong reasons, its shortcomings all the more irritating compared how good the performance actually sounds.

Opera-lovers: if you’ve finally had enough of the wheelchairs and syringes, the fifties skirts and heels, the mobile phones and the white box sets, and the rest of the symbolic paraphernalia of the right-on modern opera production, pop along to the Wales Millennium Centre in Cardiff and catch up with Michael Blakemore’s quarter-century old staging of Puccini’s great warhorse.

Roll up, dépêchez-vous, for Carmen the - what? Circus? Vaudeville/music-hall/cabaret? Opéra-ballet, post-Rameau? Not, certainly, a show subject to the kind of updated realism which has been applied by just about every production other than the previous two at Covent Garden.

David Pountney’s tenure at WNO has been an almost unqualified success, despite some eccentricities of repertoire and a certain obstinacy in the matter of new commissions. His own productions have included at least three of unforgettable quality. He has vigorously promoted money-saving co-productions like this one with Theater Bonn.

The advertising for La Nuova Musica’s Orlando billed it as “Handel’s most psychologically complex opera”. Whether or not you agree (and there are plenty of heavyweight rivals – Alcina, Giulio Cesare and Agrippina just for starters) there’s also the issue that it’s only half the story.

Vladmir Jurowski and the London Philharmonic Orchestra have been to the bottom of the Rhine before, but in 2015 only did a whistlestop tour of the rest of Rheingold's terrain with an extensive array of excerpts.

This was an evening of Iberian highways re-travelled, but with a difference. At the beginning of 2016, the centenary of Spanish master Enrique Granados's untimely death, two young pianists at the National Gallery shared the two piano suites that make up the original Goyescas; finally last night at the Barbican we got the opera partly modelled on their deepest movements.

The power of music solves every problem, at least when as bewitchingly performed as it was here. With the great mezzo Christine Rice voiceless for at least a night, and rising star Caitlin Hulcup singing for her from the midst of the instruments in the pit right at the centre of the Roundhouse, how could faithful Penelope's final acceptance of her long-lost husband Ulysses (Roderick Williams) achieve transcendence?

David McVicar may seem too gentle a soul for the lurid drama of Strauss's Salome, but his production, here returning to Covent Garden for a third revival, packs a punch. He gives us plenty of sex and violence – or at least nudity and blood – but finds the real drama in the personal interactions, the increasingly dysfunctional relationships that eventually doom all involved.

Seventy years old and still imbued with youthful flair and enthusiasm – that’s the National Youth Orchestra of Great Britain, which pioneered new territory in its first concert of 2018 last night. The flair and enthusiasm also apply to Sir Mark Elder, who conducted the event. He and the NYO, with help from Chris Riddell (former Children’s Laureate, creator of Goth Girl) and director Daisy Evans and her team, gave the first complete opera performance of the organisation’s history with Bartók's Duke Bluebeard’s Castle.
