Admirable as it was of the London Philharmonic Orchestra to launch its concerts in 2020 with a performance celebrating the Ravi Shankar centenary, the hard fact remains that this lively spectacle might have worked better without two-thirds of its players.

You can see the temptation.

There's no question about my top opera choice for 2019, especially since the London houses rarely delivered at the same pitch of engagement. It's Graham Vick's walkabout Birmingham Opera Company spectacular, a production of Shostakovich's Lady Macbeth of Mtsensk that worked on every level.

"Sadler's Wells! Any more for Peter Grimes, the sadistic fisherman?," a cheery bus conductor is alleged to have called out around the time of this towering masterpiece's premiere in 1945. The side of a "Grimes bus" today would probably proclaim over Britten and the work itself the "brand" of two stalwart perfomers - conductor Edward Gardner and leading protagonist Stuart Skelton, dominant forces of the opera over the last ten years.

Death in Venice is usually a dark and claustrophobic affair. It lends itself to small-scale staging with minimal props and suggestive, low-key lighting. But for this new production at the Royal Opera, director David McVicar has taken a different approach. He has used all the resources at the company’s disposal to create a more expansive vision.

Like almost everything that it touches these days, English National Opera’s autumn season of shows rooted in the Orpheus myth has enjoyed a fairly mixed reception. The company’s programme of visits to the Underworld concludes with another high-risk journey: Philip Glass’s 1993 opera Orphée, inspired by the 1950 film that Jean Cocteau spun from his own earlier drama on this theme.

The Beggar’s Opera: does any piece of music theatre promise more fun and deliver more tedium? Yes, it was the satirical smash of 1728; yes, it inspired Brecht and Weill; yes, with its combination of popular melodies and a topical script it was effectively the world’s first jukebox musical. I get all that.

It’s hard to believe that in 1824 there were no fewer than six productions of Weber’s Der Freischütz in London alone. Since then this colourful piece of German Romanticism hasn’t fared nearly so well, disappearing from the UK’s opera houses not just for years but decades at a time.

Advance publicity overstated the case for The Mask of Orpheus. "Iconic"? Only to academics and acolytes, for British audiences haven't had a chance to see a production since ENO's world premiere run in 1986. "Masterpiece"? Sitting there after the second interval 33 years ago, surrounded by empty seats long vacated (by fellow critics, shame on them, among others), and facing a third act with a sense of fatigue, I hardly thought so then.

Considering that Janáček’s Vixen is, among other things, an allegory of the passing and returning years, it’s appropriate that WNO continue to recycle David Pountney’s now nearly 40-year-old production, and that it comes up each time refreshed, with this or that altered or added detail, but quantum-like the same general image. This second night was like a mass family outing, perhaps because of the associated outreach event, the designs for which adorned the foyer.
