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.

You’re already in the land of the unpredictable with Pina Bausch. Creating unease was her métier. But when she pulls a gag intended to convince you that something has gone badly wrong on stage, and then it really does, the discombobulation is profound.

Lest the BBC Four imprint prove not strong enough a signal, I'll say it loud and clear: don't go into this expecting Strictly, kids. On the evidence of last night's contemporary dance showdown, the first of four section finals, the brand new BBC Young Dancer competition is light years from the razzmatazz, sparkling scoreboards and celebrity judge infighting of the BBC One dance flagship.

After the second piece of last night's triple bill, Hofesh Shechter's Untouchable in its world premiere, my friend asked me why it had been put on the programme with the first piece, George Balanchines 1946 Four Temperaments. He wondered if there was some structural or thematic connection that he had missed between the two wildly different pieces. The Balanchine speaks obviously to the bill's last item, Kenneth MacMillan's 1966 Song of the Earth; both pair a cool neoclassical choreographic idiom with deeply felt but vaguely expressed melancholy.

The premise of last night’s world première made so much sense that one almost wondered why nobody had done it before now. Commissioned by the Royal Opera House and in its downstairs Linbury space, Shobana Jeyasingh, a classically-trained Indian dancer and now director of her own contemporary dance company, would respond to the 19th-century ballet about an Indian temple dancer, La Bayadère, which has wonderful choreography but presents an entirely Western, Orientalist vision of the “exotic” east.

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.

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.

There is a special poignancy to these performances of Sacred Monsters, Sylvie Guillem and Akram Khan's terrific 2006 joint show.

How long should a dance programme be? Opera and theatre habitués can be surprised by outings to contemporary dance, where the pieces might be shorter than the intervals, and a 7:30 start could see you comfortably on the 9:15 train home. But the early train is in no danger from Rambert’s new programme, their annual showcase of contemporary creations at Sadler’s Wells, which features one world première, one London première, and one revival from this time last year, and last night came in at a handsome two and a half hours.

When you're talking about dancers, the old adage about genius being 99% perspiration has a point. You have to work damned hard just to be average in professional dance; to be good, like Akram Khan and Israel Galván are good, takes sweat (and tears and blood, like as not). Still, all the perspiration in the world won't avail if you don't have that 1% of inspiration, a little blue flame of a pilot light in your soul, ready to spark the gas jets of hard work into fiery life, rather than just a lot of hot air.
