With the eyes of musical fashion turned relentlessly on the calculating stage works of chilly alchemist George Benjamin, hopes ran high for a brighter spark in a new opera by his contemporary Mark-Anthony Turnage.

One year to Brexit, a seemingly endless winter chill and Londoners need soul food, badly. I prescribe an evening of total immersion in The Marriage of Figaro.

"The Show must go on". So say the posters dotted around Glasgow and Edinburgh for Scottish Opera's production of Richard Strauss's Ariadne auf Naxos. Except on Thursday, it didn’t. A fire at a nearby Glasgow nightclub which ravaged several city centre buildings caused the Theatre Royal to become so filled with smoke that the opening night’s performance had to be cancelled.

Engelbert Humperdinck’s Hansel and Gretel is a ‘"fairytale opera" (its composer’s description), and yet one characteristic frequently commented on is its "Wagnerian" scoring. For this production, with David Pountney’s English translation, the RNCM used Derek Clark’s reduced orchestration.

You don't have to be a good director to manage the artistic side of an opera house. Daniel Kramer arrived at ENO and boosted morale at a time when company relations with then-CEO Cressida Pollock had hit rock bottom, and his repertoire choices for the new limited seasons look fine so far.

“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.
