Emotional truth backed up by musical sophistication is what saves Puccini’s drama about a geisha deserted by an American officer from mawkishness. Director Daisy Evans has a very good idea for getting at its palpitating heart in a production of stunning visual beauty; Celine Byrne in the title role gives us vocal opulence but not nearly enough identification with a woman whose total, misplaced love leads to painful hope and desperate tragedy.

Phyllida Lloyd’s production of La Bohème for Opera North is over 32 years old but still feels young. And for its audiences it still has the ability to capture – as the opera is designed to – the experience of youthful love and separation, its ecstasy and its heartbreak.

Forget Anna Netrebko, if you ever gave the Russian Scarpia’s former cultural ambassador much thought (theartsdesk wouldn’t). It should be uphill from now on as Aleksandra Kurzak takes over the role of a diva out of her depth. Last night, though, she was unwell, and the role was taken by Ailyn Pérez, a lyric soprano who knows how to pull out all the right stops and whose dramatic truth complemented Oliver Mears’ production to perfection, presumably on little rehearsal time.

So it’s come to this: WNO’s autumn season reduced to two operas, a Tosca borrowed from Opera North and a revival of their own Candide from two years back; then two next spring. a revival of their Valleys saga Blaze of Glory (about mine closures and singers who won’t give up) and a new Flying Dutchman. And – wait for it – Tosca is with a reduced orchestra, not because some bright spark has decided to freshen it up, modernise it, but for a simpler, more compelling reason: there is no money.

At first, I had my doubts about Puccini’s Suor Angelica in this concert performance at the Proms with Sir Antonio Pappano and his London Symphony Orchestra.

At first sight, it seemed that Clonter Opera’s decision to tackle Tosca this year might be a leap too far. Its once-a-year complete production, dedicated to nurturing emerging talent in the security of the Cheshire countryside, must always be an essay in miniaturization, and a singing cast of six and an orchestra of 12 might seem hopelessly small for Puccini’s grand passions and shuddering shocks.

Before Luigi Illica wrote the libretti for Puccini’s Tosca and Madama Butterfly, he had joined the composer as the librettist in a race to stage the first production of La Bohème. The race was against Ruggero Leoncavallo, a composer Illica had once collaborated with on a libretto – for Puccini, his Manon Lescaut.

So here in Paris, as at Salzburg in 2022, it’s no longer “Puccini’s Trittico” but “the Asmik Grigorian Trittico 3-1-2”. Which would be a very bad idea if she were a lazy diva like Anna Netrebko. But Grigorian works selflessly within wonderfully strong casts. In league with Christof Loy’s viscerally demanding productions and Carlo Rizzi’s infinitely sympathetic conducting, she sets the seal on one of the greatest operatic events I’ve ever experienced.

There are no battlement leaps or murderous vows, no pistols or daggers, not so much as a slight cough disturbs the serene plot of La rondine – the Puccini opera once labelled a “poor man’s Traviata”.

This revival of Puccini’s Trittico a mere three and a half months after it was first shown on the Millennium Centre stage seems to bear witness to WNO’s current financial uncertainty. In effect, it reduces their 2024 repertory to half what it was a decade ago – four shows instead of eight, though admittedly all four productions have been new, at least to this company.
