“Would you like a veil?” asked a steward, offering a length of black gauze, and when you’re at a production by Birmingham Opera Company it’s usually wisest to say yes.

It was the work with which Handel conquered London, the Italian opera that finally wooed a suspicious English audience to the charms of Dr Johnson’s “exotic and irrational entertainment”. Three hundred years later, neither Rinaldo nor London’s audience has changed much.

A political prisoner is brutally initiated into the life of a state penitentiary, and leaves it little over 90 minutes later. Four inmates reveal their brutal past histories with elliptical strangeness - each would need an episode of something like Orange is the New Black - and two plays staged during a holiday for the convicts take up about a quarter of the action.

“What angel wakes me from my flowery bed?” Hang on a minute, Tytania, there are no flowers. Instead, as Britten’s ominously low strings slither and tremble up and down the scale, the curtain rises on a huge, near-acidic emerald green hilly slope lying against a seemingly fathomless International Klein Blue cyclorama broken only by a glowing crescent moon. Except it’s not just a hill: it’s also a giant bed; the perfect bed, in fact, in which to spend one wonderful midsummer’s night.

One question dominates any staging of Dialogues des Carmélites. How will the production team deal with the cruelty and tragedy in the 12th and last scene when all of the nuns, one by one, go through with their vow of martyrdom and calmly proceed to the guillotine, singing the Salve Regina? No spoilers here, but this new production at Guildhall School (a very different one from that staged in 2011) sticks to a tone which is calm, and humane.

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.
