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.

Pina Bausch decided: “Words can’t do more than just evoke things - that’s where dance comes in.” Well, up to a point, Lord Copper. Only if they’re bad words and good dance - bad writhing instead of, say, Shakespeare’s words isn’t much of a swap. But with Bausch, people tended to hang on every word, probably because so much of her dance was indeed pretty damn good, and it’s so difficult to put into words just why that was.

Iphigenia is an abandoned child, almost murdered by her father, lost in bewilderment, captured and indoctrinated in an artificial existence. It hardly matters that her father was the legendary Greek hero Agamemnon, her mother the notorious Clytemnestra.

A house of contact, a place to make contact - this bare, evocative title sits on one of Pina Bausch’s most appealing works, and also its most elastic. Brought this week to the Barbican posthumously, staged by her company on two amateur casts, Kontakthof didn’t look 32 years old, it looked both timeless and as fresh as fledglings cracking out of their egg shells.

Film of Pina Bausch’s dances is rare, but linked to the London performances by Tanztheater Wuppertal this week the Barbican centre is showing a season of films about her theatre as well as her working methods, capped by the famous 1985 film of Café Müller, her evocation of the restaurant in which she grew up, and in which she danced.

This week the world-renowned Tanztheater Wuppertal Pina Bausch arrives in London - for the first time, without its towering creator. Last summer the German choreographer died at the age of 68. The company intends to continue, despite the dodgy track record for troupes formed around one singular giant vision to survive long without that magnet at the core.
