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.

The challenge was already in the title for me: as both a dance critic and a strongly visual person, in the normal order of things I see the dance first and hear the music second.

^{Akram Khan is unexpectedly softly-spoken.}

^{How do you know Wayne McGregor? Dance-goers with long memories might remember Wayne McGregor as the wunderkind who founded his own company and became resident choreographer at The Place aged just 22. Lovers of contemporary dance will be familiar with his company Random Dance, which boasts some of the best dancers in the business and periodically brings sophisticated, hi-tech pieces to Sadler’s Wells.}

Grupo Corpo means Body Group, and if that sounds like the name of a global exercise consortium, it’s because it should be.

The Royal Opera House is on fire this month. Not literally (unless someone knocks over the flaming braziers outside) but with the varied illuminations of the Deloitte Ignite Festival, co-curated by the Royal Ballet and Minna Moore Ede of the National Gallery. The theme this year is Myth, and specifically Leda's rape by Zeus in swan form, and Prometheus's gift of fire to humanity.

The Edinburgh Playhouse is the largest UK theatre regularly used for dance. The stalls alone seat more than the total capacity of Sadler’s Wells, and the two circles combined seat even more again, for a maximum audience of 3,059. To see it filled almost to bursting last night for the first night of Tanztheater Wuppertal’s visit to the Edinburgh International Festival is evidence – if any were needed – that the late Pina Bausch’s company are worldwide superstars
