Rubies is a ballet for a girl comfortable with her curves, who can slink her hips and tip her bottom and relish seeing the men’s eyes widen. That the said girl is a ballerina, for whom curves are usually anathema, shows the personality challenge that this snazzy, jazzy George Balanchine ballet sets to its leading lady.

4 am. Eternal. I'm at an all-night temple festival somewhere in north Kerala in southern India - not so much in the middle of nowhere as on the outskirts of nowhere. There's wild chenda drumming and a terrifying apparition of a man who has gone into a trance – the goddess Babrakali, they tell me, has possessed him. He's wearing an outrageous red costume 12ft high, and he is charging right at me. The fact that his outfit is on fire, that he's just bitten the head off a live cockerel and the remains of the unlucky fowl dangle from his mouth, doesn't reassure me.

A modern choreographer has arrived when he gets to run two companies in parallel, the institution that appoints him director, and - as a sort of personal couture line - his own group. Wayne McGregor does it with the Royal Ballet and his Random Dance, now it’s Rafael Bonachela who took on Sydney Dance Company at the end of last year, while retaining his own Bonachela Dance Company at the South Bank Centre. Going by last night, I don't think living a bi-hemispheric existence is aiding his powers to entertain.

At last a seriously good new ballet created not just inside the Royal Opera House’s bunker-like Linbury Studio Theatre but actually making complete sense of its space and atmosphere. Kim Brandstrup’s new creation with the Royal Ballet star Tamara Rojo, Goldberg, is a beautiful, grown-up piece of fine musical feeling and drama, and with a design and lighting scheme to die for.

On Britain’s Got Talent this year Diversity and Flawless raised the bar for street dance as far as mass British audiences were concerned, a public increasingly schooled by Sadler’s Wells’ smart and eclectic annual spring hip-hop festival. So Bounce, the Swedish crew  returning to London with its 2006 version of Ken Kesey’s One Flew Over the Cuckoo’s Nest, has new standards to compete with.

Having felt thoroughly racked by Anne Teresa De Keersmaeker’s marathonian and bone-dry Rosas danst Rosas on Wednesday, I was hardly expecting charm and beguilement from the even longer Zeitung last night. But Zeitung is one of the most delightful and intelligent evenings about modern dance’s volatile relationship with classical music that I’ve seen.

There’s a sly in-joke in the plastering of Mark Morris posters over Sadler’s Wells when Anne Teresa De Keersmaeker’s Rosas are currently inside it. Morris, the waggish American choreographer whose publicity shouts “Joy, Pure Joy”, dubbed her “De Tearjerker” when she followed him into the prestigious position of resident choreographer at Brussels’ Théâtre de la Monnaie.

With five first-magnitude stars in it you're expecting at least a five-star show from Eonnagata, the collaboration between ballerina Sylvie Guillem, theatre director Robert Lepage, choreographer Russell Maliphant, designer Alexander McQueen and lighting genius Michael Hulls - possibly even the Milky Way. But I can't divvy up more than two stars for the result.
