Don’t you just love that new concert hall smell? The main hall at the Royal Birmingham Conservatoire is so new that as soon as you walk in you get the scent of fresh woodwork; so new, in fact, that it won’t even be officially opened until next month (Mirga Gražinytė-Tyla and the Earl of Wessex are doing the honours, apparently).

You have to wonder why it has taken this long. Jake Heggie’s Dead Man Walking premiered in San Francisco back in 2000 and has since been performed over 300 times across the world, staged everywhere from Cape Town to Copenhagen.

Inspired by the astonishing true story of Mehran Karimi Nasseri, the Iranian refugee who lived in Charles de Gaulle Airport for 18 years, Jonathan Dove’s Flight is a humorous, touching, uplifting yet profoundly poignant study into human relationships, interactions and emotions. This is opera buffa for the modern age – relevant, relatable, lighthearted and often downright silly, but still revealing some very pertinent truths.

Very well, so ENO's latest Gilbert and Sullivan spectacular was originally to have been The Gondoliers directed by Richard Jones and conducted by Mark Wigglesworth. But that Venetian fantasia has already been seen at the Coliseum in recent years, and Iolanthe - which I can't remember experiencing live with a full orchestra since the declining years of the D'Oyly Carte - ranges wider.

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.
