The Bolshoi Ballet's company manager, Gennady Yanin, has resigned after pornographic pictures appeared on the internet that were linked to him, just as he was being considered to take on the job of artistic director, which became vacant that day. As a result the world's largest ballet company is now leaderless, with an inexperienced dancer appointed to hold the fort.  SEE LATEST NEWS: Sergei Filin appointed artistic director for five years

Let's get the obvious out of the way: yes, this is incredible. Not just the sounds, nor the ambitious staging of Hans Christian Andersen's last story as a ballet, but the fact that, 30 years since they met, Neil Tennant and Chris Lowe are still making music that's both relevant and gloriously excessive to a frankly crackerdog mental degree. They've tinkered with classical themes before, of course, from setting “Che Guevara and Debussy to a disco beat” in 1988's “Left to My Own Devices” to their 2004 live soundtrack to Battleship Potemkin, but this is something else. Piling on romantic themes and electronic beats of various flavours, it leaves no stone unturned in finding the most over-the-top fairytale themes, then ornamenting them and ornamenting the ornamentation of the ornaments until the whole thing is a kaleidoscope of whirling, twirling synaesthesic madness.

You thought Black Swan was a nightmare depiction of the ballet world? Now watch Agony & Ecstasy: A Year With English National Ballet, Part 1 and squirm. Compare Natalie Portman’s tormenting balletmaster with ENB’s Derek Deane, as each of them stages Swan Lake. One tells his ballerina she’ll need to masturbate to discover her inner black swan; the other one contemptuously dismisses his ballerina as too old, too knackered, past hope.

Hot on the heels of the Pet Shop Boys’ foray into ballet for Sadler’s Wells next month, it’s revealed that Sir Paul McCartney has composed a ballet for New York City Ballet, a love story called Ocean’s Kingdom.

Scheduled to premiere on 22 September, the four-act ballet so far has 45 minutes of music, and a cast of around 40. The New York Times reports that the first act is having its first run-through next Thursday at the Lincoln Center, NYCB’s home stage.

Aylesbury, a town without a theatre, has built itself one - a gleaming, glass-fronted, smack-you-in-the-eye 1,500-seater, driven and supported by the district council. High Wycombe and Milton Keynes must beware, so thin are the pickings these days for the regional theatres. The pity is that the Ballet Boyz’ show The Talent last night was the only night of decent dance programmed in this amazing new venue for half of 2011.

Whether it’s consolation, stimulation, or just some old-fashioned romance you’re after this Valentine’s Day, theartsdesk’s team of writers (with a little help from a certain Bard from Stratford) have got it covered. Exhibitions to stir the heart, music to swell the soul, and comedy to help recover from both – we offer our pick of the most romantic of the arts. So from Giselle to Joe Versus the Volcano, from Barthes to the Bard, theartsdesk celebrates the many-splendoured thing that is love.

What a difference 24 hours can make. The first night of ABT’s pick‘n’mix season – 10 ballets in six days – veered from “fine” on downwards. Another opening, another show, though, and things have picked up very nicely indeed. Ballet Theatre has on display in this programme its peerless historical range, from Antony Tudor’s Jardin aux Lilas (mounted on the company in 1940), through Balanchine’s Theme and Variations (choreographed for them in 1947), his 1960 Tchaikovsky Pas de Deux and finally, and most wonderfully, Paul Taylor’s miraculous Company B: a piece that makes you want to dance, to sing, and fills you with a sorrowing pity, all at the same time.

Was it the worst-played and worst-danced performance of Duo Concertant I’ve ever seen? I can’t remember a direr in my experience of quite a few DCs. But then the opening night of American Ballet Theatre’s London tour was a set of fine promises falling flat with a thud. A delicate new sextet ruined by the piano player. A masterpiece of musical ballet murdered by the violinist, the pianist and the ballerina. A cod-ballet duet by Twyla Tharp deflated by an unhumorous leading lady. And the only tick - inasmuch as at least the dancers gave it what it needed - was a piece of ensemble window-dressing that ticked the “modern” boxes that used to pertain two decades ago.

"You have to start somewhere," remarked Debussy drily at the 1910 premiere of young Stravinsky's Firebird ballet. Even so, that was far more of a somewhere than the ultra-nationalistic Hungarian tone poem Kossuth, first major orchestral flourish of Béla Bartók, the Russian's senior by one year. In choosing it to launch Infernal Dance, the Philharmonia's 2011 celebration not of Stravinsky (as the title weirdly implies) but Bartók, principal conductor Esa-Pekka Salonen showed how far his main Magyar travelled to works like the hyper-percussive First Piano Concerto and the ballet-pantomime The Miraculous Mandarin, a work strident and fresh enough to serve as potential soundtrack to the so-called life of a latter-day wreck like Anna Nicole Smith.

The return of the Royal Ballet’s Swan Lake production coincides with the tumult over the film Black Swan, about which the company’s marketing department must be pretty pleased, even if some of the dancers aren’t. The chief surprise for any newcomers drawn to the ballet by the film, obsessing as it does about the leading ballerina, must be how long it takes to meet the Swan Queen at all.
