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.

When Yasmina Reza’s cerebral play Art arrived in London in 1996, we applauded it as a comedy. Now another French hit, Jean-Philippe Daguerre’s Adieu Monsieur Haffmann, has landed, and the genre confusions could start all over again.

Taking on some of the contingent, nebulous quality of its subject, Jacqueline Feldman’s Precarious Lease examines the beginning and the end – in 2013 – of the famous Parisian squat, Le Bloc, thinking through the triumphs and consequences of the unique leniency that Paris had shown towards the preservation of such indeterminate spaces.

Just now, music about survival, transcendence and the afterlife may have a special resonance for the BBC Singers. After all, the supremely versatile century-old chamber choir has endured its own near-death experience – at the hands of the BBC top brass who, in 2023, planned to axe them.

There are two main reasons to revive classics. The first is that they are really good; the second is that they have something to say about how the world is changing, perhaps more accurately, how our perception of it is changing. Both are true of Annie Kershaw’s slick, sexy, shocking production of Martin Crimp's translation, up close and personal, at the Jermyn Street Theatre.

As Bono once commented about Luciano Pavarotti, “the opera follows him off stage”. Legendary soprano Maria Callas would have known exactly what he meant, and she herself said “an opera begins long before the curtain goes up and ends long after it has come down.”

Enough is as good as a feast, they say. But sometimes, especially at Christmas, you crave a properly groaning table. At the Wigmore Hall, The English Concert, directed by Harry Bicket, concluded their festive Baroque banquet with Bach’s Magnificat – complete with its four Christmas-tide interpolations. They had prefaced the Bach with a trio of lesser-known seasonal pieces dating from the preceding decades, by Charpentier, Stradella, and Purcell. That might sound like a light plate of rather scholarly, even austere, hors d’oeuvres.

You might assume that the “Has Fallen” in the title of this Anglo-French thriller connotes the presence of Scottish lunk Gerard Butler (as in Angel Has Fallen, London Has Fallen and Olympus Has Fallen), but there’s no Gerard in sight. Instead, in this TV spin-off from the movie series, we have Tewfik Jallab (pictured below) as protection officer Vincent Taleb, who’s acting as minder to France’s defence minister Philippe Bardin (Nathan Willcocks).

For his latest pick’n’mix sortie into the world of the women’s picture, François Ozon has gone back to the 1930s and a popular play of the time, Mon Crime (1934). In his hands it emerges as an île flottante of a film that slips down easily but isn’t that nourishing, even though he adds some crunchier elements along the way.

Brazilian artist Lygia Clark is best known for taking her abstract sculptures off the pedestal and inviting people to interact with them. Dozens of constructions named Bichos (Beasts or Critters) (pictured below right) are hinged along the joins to allow you to rearrange the parts in seemingly endless configurations.
