One queen is much like another in so-called “historical” Italian early to mid 19th-century opera. Elizabeth of England, Christina of Sweden, take your pick, they all fall for a tenor courtier who loves Another (the seconda donna, soprano or mezzo). With Donizetti, the musical drama is almost as disposable as the plot until a stonking number or two rolls up. Jacopo Foroni, more or less unknown until Wexford resurrected him a year ago, has a few more felicitous orchestral touches but nothing as memorable as Donizetti's best.

Dvořák’s rustic operetta sits, swinging its legs rather diffidently, historically somewhere between the neverland Bohemia of Smetana’s The Bartered Bride and the lacerating reality of village life in Janáček'’s Jenůfa. The Cunning Peasant’s charms lie in its string of sophisticated songs and dances, more through-composed than Smetana’s, and in the abundance of not over-taxing roles, as well as chorus numbers, it offers to students.

Of course unavoidable circumstances do strike, and concerts do get delayed, but it’s astonishing just how often those circumstances seem to conspire against Valery Gergiev. Last night’s UK premiere of Rodion Shchedrin’s opera Levsha – the second night of a Mariinsky triptych of performances at the Barbican – started a nice round hour late, which was a real shame because once the drama shifted from offstage to onstage the work revealed itself as a bit of a gem.

God-sent sea monsters and divinely ordained human sacrifices don’t wash well with opera updated. The favoured contemporary take on the post-Trojan War myth of Mozart’s Idomeneo, which may even have originated in the last Covent Garden production 25 years ago by a fitfully brilliant Johannes Schaaf, has been to put a populace at risk from natural disaster and pestilence. Clearly the programme was expecting something of the sort, with its images of Hurricane Katrina. But no, for director Martin Kušej, the only monster is the state.

It’s one of the ironies of life and art that Prokofiev’s tenderest and most romantic opera was composed at a time when he was abandoning his wife in favour of a Moscow literature student half his age. Betrothal in a Monastery is a setting in Russian of an opera libretto by Sheridan about the attempt of a Spanish grandee to marry off his young daughter to an elderly fish merchant. Like most comic operas, and some not so comic, it’s set in Seville; the wife Prokofiev was walking out on was Spanish.

ENO may not always have matched the Royal Opera in the Great Puccini Voices stakes. But it's served up many of the classiest Mimìs, with Valerie Masterson, Mary Plazas and Elizabeth Llewellyn as top seamstresses. Californian former beauty queen Angel Blue, an acclaimed Musetta in the previous revival, now joins them.

It takes a brave man to programme a single performance of Berg’s Wozzeck on a damp Thursday evening in Glasgow. But Donald Runnicles is such a man. In his five years at the helm of the BBC Scottish Symphony Orchestra he has proved adept at making the implausible possible, and turning the ordinary into something extraordinary.

You may be more familiar with the Italian title, Il mondo della luna, but chances are you won’t have seen this or any of Haydn’s other 16 operas. You haven’t missed much, at least until the last of his works as court composer to the Esterházy family, Armida, an "heroic drama" rather than the slim comedies which don’t seem to have inspired the composer to the heights of his symphonies and string quartets.

To take Figaro – the ultimate operatic assault on class distinctions and social hierarchies – and set it on a giant revolve is a gesture as wilful as it is elegant. Not only are divisions of above and below-stairs dissolved in this steadily circling world, but also those of background and foreground, onstage and offstage. By the time the set’s rotations revealed two young valets with their trousers down, relieving themselves up against a palace wall, some few minutes into the Overture, Fiona Shaw had already won her audience and her case.

First the good news. At 73, is Plácido Domingo anywhere near retiring? Er, no. When the question came up in an interview on Sunday (on video below), he answered : "The reason I don't retire is because I can still sing." And then with a glint in his eye: "I still feel I have to know the the right moment. Not to sing one day more.... nor one day less."
