No, don't check your calendar – it's definitely not March. I associate flamenco at Sadler's Wells so strongly with their annual two-week festival in early spring that watching Paco Peña Company at the Wells last night felt a bit like a cheeky out-of-season treat, akin to buying foreign strawberries before the native ones have come in. Fortunately, this was no watery, bland, forced berry, though: Peña and friends are some of the best in the business, purveying reliably high-quality goods in smart, well-produced packaging.

Sylvie Guillem is retiring in exactly the same way as she does everything: in her own time and on her own terms. She turns 50 this year, but it’s not that age is finally catching up with her – at least, not in her body, which she acknowledges has potentially many more years of dancing in it.

After the disappointment of Wayne McGregor’s latest piece for the Royal Ballet, which opened on Monday, I thought last night’s trip to Sadler’s Wells for a new Rambert programme might cheer me up about the state of contemporary dance and composition. Two new pieces were on offer, by rising choreographer Alexander Whitley and Rambert director Mark Baldwin with original scores by Icelander Daniel Bjarnason and Brit Gavin Higgins respectively, alongside a revival of Lucinda Childs’s Four Elements, and there was no sign of the fawning hype that preceded the McGregor opening.

Composer Gavin Higgins and choreographer Mark Baldwin’s Dark Arteries is billed by Rambert as “the world’s first brass band dance work” and has its premiere this week at Sadler’s Wells. Higgins was born into a family of brass players in the Forest of Dean, later studying at Chetham’s School and the Royal Northern College. He spoke to theartsdesk in between rehearsals last week.

GRAHAM RICKSON: How important was music-making when you were growing up?

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"?
