Has the great pop diva Beyoncé plagiarised the great modern dance diva Anne Teresa de Keersmaeker? This is the burning question that has today sent disco popsters and fans of austere contemporary dance in a feverish crush to YouTube, comparing Beyoncé’s new "Countdown" vid with De Keersmaeker’s art-house dance Rosas danst Rosas. They’re turning over micro-flashes of Beyoncé, running them back, comparing them with… well, you have plenty of choose from, as De Keersmaeker doesn’t believe in throwing away her ideas in 10 seconds.

“Jazz is my adventure,” said Thelonious Monk. “I’m after new chords, new ways of syncopating, new figures, new runs. How to use notes differently. That’s it. Just using notes differently.” Based on the title of the new hour-long piece by Israeli choreographer Emanuel Gat, Brilliant Corners, named for Monk’s 1957 album, the naïve viewer might expect, at the very least, to hear some Monk. Not so. Gat has produced an always interesting, sometimes absorbing sight-and-sound world, but of Monk, or jazz, there is neither sight nor sound.

It takes more than utmost craft and rich personality to hold the stage as a soloist - it takes a touch of divine self-belief, which Akram Khan has never displayed to more magnetic effect before than in his new solo DESH. Actually solo is too small a word for this epic, lavish display of the starpower that Khan now emits in the world of dance theatre.

Dance is eating itself. Or dancers are eating themselves, rather. It's on-trend to defy the idea of the mute dancer, and instead have them verbally explaining themselves, their motivation, their art. This year’s Dance Umbrella launched last night with the “self-contemplation” of Cédric Andrieux, a handsome blond Frenchman, who regales us in a charming murmur for 80 minutes with the story of his career, with danced illustrations.

The clips as you load the DVD show women in extremis - women tied to the end of a rope, women being assaulted by mass male groping, women dancing on pointe with bleeding chunks of meat stuffed into their ballet shoes. Pina Bausch’s commentaries on women make her ballets disquieting viewing. Wim Wenders’ film, released as a 3D version in cinemas earlier this year, takes you into those deep, confused questions that Bausch’s dance works put.

As artificial spaces, clubs struggle to embrace the organic environment. The music and arts collective Noise of Art are bridging the gap by working with the charity Trees for Cities, with DJs donating their time to raise funds for planting trees in London. On 17 September, Noise of Art is working with Trees for Cities at Battersea Park and taking over the Village Underground for a fundraising event.

Only three years ago, Hofesh Shechter, the Israeli-born, London-based choreographer, made the leap into the big leagues, almost overnight, with his Uprising/In Your Rooms double bill. The following year he produced a "Choreographer’s Cut", a bulked-up version in the Roundhouse, part dance, part gig. 2010’s Political Mother was received with rapture, so what next?

It’s not often that a venue’s stage door is easier to find than its main entrance, but The Old Vic Tunnels is one such location. For those behind Coming Up Later, however, this is all part of the fun of a three-evening underground festival featuring a rather wonderfully haphazard range of performances. The event is the product of The Old Vic’s outreach programme, Old Vic New Voices, and the funding and artistic crowd-sourcing network IdeasTap.com. Such collaboration resulted in an opportunity few emergent creative directors could ignore: a production team, a budget to play with and three expansive tunnels for those who could imagine how best to use them.

Yesterday was a day when male physicality and the science of movement preoccupied - when you watch Rafa Nadal or Jo-Wilfried Tsonga, you can’t help thinking about the contrasts of grace that achieve the same athletic needs; Nadal the pouncing cheetah, the rich, weighty speed of Tsonga. Thing is, when you watch programmes about the greatness of tennis, they don’t try to persuade you that it’s just as good to watch if you yourself learn to play and get it filmed for the public's delight.

Last March’s Japanese earthquakes and tsunami, as we know, brought devastation to hundreds of thousands of Japanese. But it also caused a crisis in the 3D film industry, just as it is attempting to be born. The most important 3D tape stock finishing factory in the world was swept away by the waters.
