Ambika P3 is a windowless, cavernous basement once used to test concrete for huge building projects – the Channel Tunnel among them – now ingeniously recycled as a kunsthalle gallery / performance space.  Thus it is strikingly appropriate for its current incarnation.

Quite simply, the performance was one of those rarest of events in the theatre that will be talked about for generations - the Russian premiere of Kenneth MacMillan’s Mayerling, with the former Royal Ballet star Sergei Polunin making his debut as Crown Prince Rudolf.

Jewels, gold, silver, arms and armour, silks, embroideries, tapestries and lace: the world of the very rich and very powerful royals – and merchants – in Russia and Britain half a millennia ago is set out in glittering array in the V&A’s latest exhibition. The English imported fabulous furs from Russia, delighting in the finest sables, but also wood, hemp and tar, the better to build British ships. The Russians acquired beautifully crafted objects and above all arms, a perennially sought-after commodity which the British were skilled at supplying.

So the man who specialises in dancing Bolshoi ballet villains has been arrested and confessed to the infamous attack on his boss, Sergei Filin. But today Pavel Dmitrichenko, well-known to Bolshoi audiences for playing Ivan the Terrible, one of Russia's more pitiless Tsars, showed an equally Tsarist haughtiness when he made his first appearance in a Moscow court. He had nothing to apologise for, he said, even though it's emerging that at the very least Filin, a 42-year-old father of three, will never see normally again and his future employment must be in doubt.

Orchestral volcanoes were erupting all over Europe around the year 1915. It was courageous enough to make a mountain chain out of three of them in a single concert. I was less prepared for the white-heat focus applied by that stalwart Dane Thomas Dausgaard, and completely flummoxed when he and Jian Wang, a cellist with the biggest yet most streamlined sound I’ve ever heard, made total sense of the only overblown monster on the programme, Bloch’s "Hebraic Rhapsody" Schelomo.

You don’t have to live under a totalitarian regime to write music of profound anguish. I was driven to argue the point at a Shostakovich symposium when an audience quizzer took issue with my assertion that Britten could go just as deep as the Russian. Much as the works of the two composers in this programme, Shostakovich’s Second Piano Concerto and Britten’s Spring Symphony, revealed their lighter sides to varying degrees, it was our anniversary composer who scored highest with his darker undercurrents.

Studying Russian for three years to read Pushkin’s verse-novel Eugene Onegin in the original doesn’t guarantee the finest interpretation of Tchaikovsky’s equally great lyric homage. Yet it certainly seems to have focused the imagination of Covent Garden’s new Director of Opera, Kasper Holten, and allows him to inflect every move his characters make with the right emotion.

Joe Wright’s screen adaptation of Tolstoy’s giant of a masterpiece, scripted by Tom Stoppard, takes a big risk that pays off: the many-layered late 19^th-century novel is stripped to its bare bones with astonishing brio. He sets most of the story in a theatre, playing with the illusion created by a proscenium arch and the mirrored worlds of audience and stage.

The Mikhailovsky Ballet's general director, Russia's fruit tycoon Vladimir Kekhman, may just have been declared bankrupt, but the company is pressing ahead with its star-studded London trip in March. 

Fraud investigators last week raided the offices of the Mikhailovsky, St Petersburg’s “other” company (ie, not the Mariinsky), looking for connections between Kekhman's business activities and the theatre. Nearly six years ago the "Banana King" became the 180-year-old theatre’s general director and donated a billion rubles to fix its crumbling walls and renovate its programme.

Bolshoi Ballet director Sergei Filin has vowed to return from the horror of an acid attack to lead Russia's flagship ballet company - "not handsome, but in full force", in a remarkable interview from his hospital bed. Facing two solid days of surgery on his eyes and head, seriously burned by sulphuric acid thrown over him by a masked man last Thursday night, Filin said he urgently hoped the police would solve the crime, or he would lose faith.
