Genius is as genius does, and Rudolf Nureyev made sure nobody was left in any doubt about the scale of either his talents or his ambitions.

There's now something of a gala atmosphere when the Orchestra of the Royal Opera House takes to the Covent Garden stage with its music director Antonio Pappano. Admittedly some of the players are not the same as when he took up his tenure, but the core relationship of 17 years - with the contract now extended to at least the end of the 2022/23 season - results in collegial music-making at an intense level which most orchestras can only dream about.

There is no doubt that this Cherry Orchard, whirled into town by Roman Abramovich from Moscow, is going to be divisive. If you, like the two elegant old gentlemen sat next to me on press night, have come to see the Pushkin Drama Theatre’s production in order to steep yourself in Chekhov’s philosophical ambiguities and perhaps brush up on your Russian, you will be disappointed.

In the fourth performance of their UK tour, with Vassily Sinaisky replacing an indisposed Yuri Temirkanov, the St Petersburg Philharmonic gave a warm and rousing performance at Symphony Hall, Birmingham.

Is there a connection between revolution and theatre? The answer has to be yes – a visceral one. The supremacy of symbols, the collective strength of a crowd, a sense that some kind of pressure valve is being released to challenge the dominant social narrative. The Ancient Greeks understood this – it was from such impulses that theatre had its birth. So how does that work amid the populist turbulence of the twenty-first century?

Russian trio Gnoomes have created small waves over the last couple of years with their woozy psychedelia. One of its defining factors is the way the band have utilised Soviet-era synthesizers. During the Cold War it wasn’t only weaponry and the space race that defined the endless competitiveness between the United States and the USSR; the technologies of sound were also an area of rivalry.

Diversity, and the need for more of it, is a hot potato in the theatre arts. Kudos, then, to English National Ballet and its director Tamara Rojo for the 23 nationalities represented within its ranks. And for the poster advertising the company’s current revival of Swan Lake which pictures African-American first artist Precious Adams in swan queen pose. But hold the applause for a moment.

It is 1914 – a fateful year for assassinations, war and revolution. The fictional Erast Petrovich Fandorin, the protagonist of Boris Akunin’s series of historical thrillers, is an elegant, eccentric sometime government servant, spy and diplomat, as well as engineer, independent detective and free spirit.

There’s a welcome alternative to panto hijinks in this gem of a Trevor Nunn musical revival – more attuned to the biting hardships of winter, and to the elegiac aspect of change, than to festive jollies. Which is not to say that there isn’t rousing fun to be had in many a slick set-piece, but this intimate, sensitive staging brings out the work’s soul, particularly its timeless call for empathy and compassion.

It is appropriate that Keanu Reeves sounds especially croaky and muffled throughout Siberia. Business meetings for his character Lucas Hill (a diamond trader) don’t normally involve much talk, just a swift briefcase handover and a confidential handshake. He is forced to get engaged, however, when his partner Pyotr (Boris Gulyarin) disappears, forcing him to travel to Russia to meet with the clients and track down his colleague.
