Retrospectives are difficult in dance, and for Pina Bausch's brand of Tanztheater, even more difficult. A great deal of her oeuvre's impact derives from the special atmosphere of her Wuppertal company, whose dancers were devoted to her and to each other, in many cases staying for their whole careers.

From Singin’ in the Rain and Anything Goes to Hello, Dolly! and Mary Poppins, Olivier Award winner Stephen Mear has done more than any other British choreographer to usher classic musicals into the modern era. But adept as he is at razzle-dazzling ’em, there’s more to Mear, as recent excursions like City of Angels at Donmar Warehouse and Die Fledermaus for the Metropolitan Opera prove.

Your mum told you (or at least, I hope someone did) that it wasn't about being pretty, it was about having personality. True wisdom though this is, you probably also noticed that there are some jobs where it appears to be necessary to conform to a certain model of style or appearance. Playing the princess roles in ballet is one of these, though it's not about prettiness: for practical reasons you have to be shorter and considerably lighter than the men who will partner you.

Even for a dancer of Akram Khan’s sublime gifts, “Now” is an evasive concept to convey. During last night’s Sadler’s Wells extravaganza of Azerbaijani jazz and contemporary dance, “The Pursuit of Now”, Khan and his co-performer, the German-Korean dancer Honji Wang, mesmerised in a series of vignettes, gorgeously choreographed and lit. Azeri pianist Shahin Novrasli, whose ensembles’ charismatic folk-jazz comprised far more of the programme than the dance, offered a compelling snapshot of the Azeri music scene, beautifully positioned between Eastern and Western traditions.

Reviews of English National Ballet in which I rave about what Tamara Rojo is doing for the company are getting to be the norm round here. This one is no exception, and I'm not even going to apologise for it.  Last night was the opening of Modern Masters, an ambitious new bill in which the company more than prove they're up to handling the big beasts of late twentieth-century choreography.

"Sprung from pure flamenco, Manuel Liñán exudes purity from himself and his dance - he is life, freshness and passion."  Leaving aside the need for a better copywriter, or at least translator, what does this, the opening line of the flamenco performer's biography in the programme for the Sadler's Wells Flamenco Festival, tell us about him?  That he's not afraid of making big claims, certainly. That he may have a teeny bit of a god complex ("sprung from"?

The Sadler's Wells Flamenco Festival is cunningly scheduled for that particularly dreary fortnight in late February when winter has been going on forever, spring is still just out of reach, and half term brings the dismal realisation that we're only just halfway through the school year and summer holidays are still at least five months away. When you're longing to be somewhere else, there's nothing like flamenco, a raw, gritty music-and-dance form born among the dispossessed of southern Spain.

The Associates is not the title of a new Scandi crime drama, though in dance world terms we’re perhaps approaching that level of Event. Associates are what Sadler’s Wells, London’s dance powerhouse, calls the selected band of dancemakers it deems serioulsy interesting, and worth co-commissioning.

One of the dance world's better-kept secrets is the existence of a brilliantly inventive comic double-act consisting of two paunchy, balding 50-something men. Neither humour nor the over-50s are seen all that often in dance, but it isn't tokenism which makes dance insiders turn out in delighted force for choreographer Jonathan Burrows and composer Matteo Fargion: it's the knowledge that Burrows and Fargion's shows are one of the surest bets in dance for an evening that will be original, funny and clever in equal measure.

Testament to the work of Richard Alston Dance Company (RADC) over the 20 years since its foundation was not just the première-filled celebratory programme performed at Sadler's Wells last night, but the enthusiastic audience there to see it. Alston's own choreography never excites me particularly, but there's no denying his company has done sterling work for the British contemporary dance scene over the years, both through its association with the Place and London Contemporary Dance School, and through its extensive regional touring schedule.
