It is proof, as if more were needed, of how very right-on Birmingham Royal Ballet’s director David Bintley is, that he chose to open the International Dance Festival currently taking place in that city with two specially commissioned ballets from emerging choreographers who started their dancing careers with the company: Quatrain by Kit Holder and Kin. by Alexander Whitley.

How silly is ballet allowed to be? It is a question that is not, well, as silly as it looks. English National Ballet’s director, Tamara Rojo, has set out her stall with a glitzy production of this 19th-century classic, her first full-length commission for her new company. What she’s selling from that stall, however, is moot.

It has been said that Mozart, so prodigiously talented so young, seemed to be merely a vessel through which God, or the music of the spheres, or whichever higher being one chooses, channelled the sounds of heaven. So, too, sometimes, does Balanchine appear to be a vessel through which music is channelled, to take solid form in front of our eyes. And never more so when the music in question is Tchaikovsky.

Money, love, professional jealousy - the three undying motives for personal crime, and all three were present in the Bolshoi Ballet acid trial. An international public that scoffed happily at the OTT ballet horror-show that was the film Black Swan was suddenly sobered up by real-life events that needed no cinematographers and screenwriters.

Even by the grand Guignol standards of Russian ballet 2013, this week has been eventful. The trial of the Bolshoi dancer for attacking his boss with acid finally began on Tuesday, and with incredible, tension-ratcheting synchrony, the controversial, mouthy Bolshoi star who was fired in the summer for machinating against his leaders has been appointed to head Russia's world-famous ballet school.

Sometimes it’s better to be lucky than good. Sometimes, of course, it’s even better to be both. And Birmingham Royal Ballet, in their all-too-brief London season, have been both lucky and good. Lucky, because they have Peter Wright’s little jewel of a production to dance; and good because, well, they’re good in it.

The opening night of the autumn season brings a gala first night, Carlos Acosta’s staging of Petipa’s Hispano-Russo-Austro-Hungarische castanet-fest, Don Quixote, with starry leads (Marianela Nuñez and Acosta himself), a very obviously expensive new production courtesy of West End musical designer Tim Hatley (Shrek and Spamalot), and an amped-up re-orchestrated score from conductor Martin Yates.

The Bolshoi’s summer season in London has so far been straight-down-the-line trad: Swan Lake as an opener, Bayadère, Sleeping Beauty. Now, however, with Balanchine’s Jewels, they’ve at least dipped a pointe shoe into the 20th century, if rather cautiously.

The Bolshoi Theatre reopened in late autumn 2011 after a problematic six-year refurbishment said to have cost a tidy billion dollars, many times its original estimate thanks to corruption - it needed a corker of a ballet premiere to pop the eyes of a cynical Russian public, and it set upon a new staging of The Sleeping Beauty. This was also problematic, as three years earlier it had been promised to the then ballet director Alexei Ratmansky, who had soon afterwards resigned his job, wretched and miserable with the corrosive relationships within the theatre.

The mighty adorable Carlos Acosta is at the London Coliseum this week in all his might and all his adorableness - four times, you may like to know, he appears without his shirt on. This is relevant, because it’s not the preening bare-chestedness of a showbiz egomaniac like some I could name, it demonstrates the desire of a man to shed trappings, to be himself at his most unadorned, adorning the art he loves: classical ballet.
