An inviting gap in the market, a dark, mysterious place, was left beckoning when the dance theatres of Britain cashed in on expensive refurbs in the name of public accessibility. Putting an end to mystique, they homed in on IKEA style, all glass, pale wood and airport foyer briskness. The theatre as a continuum with our office space, blank, unprejudicing, unintoxicating, all about efficiency and the bottom line.

Why does Natalia Osipova, one of the world's best classical, dramatic ballerinas, want to start a sideline in contemporary dance in the middle of her career? Two years ago, when she mounted her first self-commissioned contemporary triple bill with her then newly-ex-fiancée Ivan Vasiliev, I was willing to believe that it was for the love of trying new things, pushing her own boundaries, and taking all aspects of her artform seriously.

I could tell you what the German word "Betroffenheit" means by giving a dictionary definition, etymology and connotations and so on. But I won't, because this dance-drama hybrid by Jonathan Young and Crystal Pite is precisely not about pinning down definitions or making sense through words in a descriptive, iterative sort of way, but about capturing feelings or states of being in a much more metaphorical, experiential, immersive way. Betroffenheit is in one sense, then, the feeling you have after watching the show Betroffenheit.

Hearing that both Javier de Frutos and rabbit heads appear in the new BalletBoyz bill might give you pause. A choreographer so unafraid of graphic content that he started his career with naked one-man shows, and later made a piece about the Pope so sexually explicit and offensive that he got death threats – do the rabbit heads mean we're in for some kind of furvert orgy?

International Dance Festival Birmingham (IDFB) is one of the unsung heroes not just of dance in Britain, but of festivals. It treats anyone within striking distance of the West Midlands to an exciting range of performers and public dance events over three weeks, and is cleverly scheduled in May – when lengthening days and bank holidays make us want to go out and have a good time, but it's not quite warm enough for camping.

Charles Linehan is an acclaimed British choreographer, whose company has performed all over the world, from DanSpace New York to Brussels’ Kaai Theatre to the Venice Biennale. Born in Cyprus and raised in Kent, he studied at the Rambert School of Ballet and Contemporary Dance, prior to honing his craft as a dancer with various European companies.

This new run of Kaash is an interesting test case for Akram Khan Company as its eponymous founder approaches his retirement from stage performance (forecast for next year). Kaash was Khan's first full-length work, created in 2002 and widely acclaimed at the time. But can Khan's older work stand up after 14 years in which Khan has consistently supplied the British dance scene with some of its most riveting shows (DESH, Gnosis, Sacred Monsters)?

Choreographers are not generally household names, but Matthew Bourne must come close. Not only does his company tour frequently and widely, with a Christmas run at Sadler’s Wells that many families regard as an essential fixture of their seasonal celebrations, his pieces have also been seen on Sky, on the BBC, and on film, most famously when his Swan Lake featured at the end of the 2000 movie Billy Elliot. This month he’s set to become even more widely known, as a film version of his show The Car Man is shown in dozens of UK cinemas.

Sitting near the front at a Pina Bausch piece always provokes anxiety.

If you thought circus acrobats and Shostakovich were a daring combination, try circus acrobats and Monteverdi. While the spiky harmonies and vivd dynamics of 20th-century Russian string quartets sit pretty nicely with circus show-offery, surely Baroque music, with its steady continuo basses, its measured rise and fall, is a world away from tumbling tricks and strongman stunts?
