“As Gregor Samsa awoke one morning from a troubled dream, he found himself transformed in his bed into a monstrous insect.” In one of the most famous opening lines in literature, Franz Kafka gives birth to a startling hallucinogenic premise. And Arthur Pita’s very clever dance drama produces something of a similar jolt in its precision and strangeness.

Is the Bolshoi Ballet going to have trouble selling its tickets for its London tour as a result of the acid attack on its artistic director Sergei Filin? A range of opinion is erupting among ballet-goers dismayed not only by the attack but by the exposure of vicious infighting inside the Moscow troupe and the subsequent public developments.

Ballet Black open their eighth Linbury Studio Theatre season with a quadruple bill of new works which looks promising on paper but less so in actuality. The evening begins with Robert Binet’s EGAL, the title being a (now obsolete) Middle English word meaning equal, which Binet used as the piece’s crux. The work is a duet that’s meant to ‘"xplore the possibilities and complications that might arise if two people who are completely equal in every sense and ability were to encounter each other".

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.

I've always keenly anticipated Derevo. A rare sight in London, they are the must-catch company in a singular branch of mime theatre - some would call it clowning, from an oblique, dark place of visions, fears and childlike imaginings. They are a small monkish Russian troupe who with apparent heedless aim have for the past 25 years been snatching at history, fantasy, antique commedia dell' arte, and the rubbish-strewn street in productions that often leave your brain spinning with questions but your heart twanging with comprehension.

It’s hard to work out why the Royal Ballet has not indulged in more Jerome Robbins, so eminently suited does it seem for their taste for emotional understatement. In the Night had a few outings in the 1970s, and has only now been revived, possibly after seeing the audience response to the Mariinsky’s immaculate performance of the same in London a year ago.

Few singers provoke more debate than Rolando Villazón. His off-piste projects - from his Romantic exploration of the Baroque to his spell as a talent contest judge - have been much discussed over the years. By comparison, there's something strangely calm and conventional about Villazón's two latest projects: a new album of Verdi on Deutsche Grammophon and a performance of John Copley's La Bohème at the Royal Opera House. Yet you'd be foolish to ignore either.

So Tony Hall moves from heading the Royal Opera House to taking over the BBC as its new Director-General. I can't for a moment imagine a rerun of that crucial mini-conversation between Helen Boaden and George Entwistle over the Jimmy Savile programming (if you can remember all the way back to mid-October through the cannonfire since) taking anything like a similar course had it been Tony Hall rather than Entwistle.

Make no mistake; this is dancing of the highest order. The classically trained members of Wayne McGregor's company Random Dance demonstrate such exceptional mastery of technique that their movements should have one drooling in admiration. And since they wear little more than vests and pants for this production of FAR, every muscle in their perfectly honed bodies is visible as it tenses and releases, flexes and extends.

A new Liam Scarlett ballet has become an event, even as, in this case, Scarlett’s home company, the Royal Ballet, is recreating a work he choreographed last January for Miami City Ballet – the young choreographer’s first international commission.
