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.

Madness is a favourite trope of opera, less so of ballet. There’s Giselle, but her insanity lasts only a few minutes. There’s Kenneth MacMillan’s delusional Anastasia, who believes she's the daughter of the last Tsar of Russia, but the advent of DNA testing destroyed the story’s credibility.

This morning, those who follow ballet on both sides of the Atlantic might be feeling a bit like the male soloists at the beginning of Ashton’s Scènes de Ballet: turning their heads sharply, almost pantomimically, from side to side. Over there, in New York, Wendy Whelan, the prima ballerina retiring after a 30-year career with City Ballet, made her farewell in a programme heavy on modern masters Wheeldon and Ratmansky, including a world première.

Thirty-year-old Rocío Molina has been rattling cages in the hide-bound world of flamenco. Back home in Spain, gloom-mongers are predicting she’ll bring down the art form with her brazen, off-the-leash excursions from its honoured tropes. Her shows are popular. And the fluorescent four-inch heels and electric bass guitar that feature in her latest – brought to London for three nights by Dance Umbrella, following a storming reception in Seville – will have done nothing to reassure traditionalists.

^{New Adventures, the name of Matthew Bourne's company, has a ruddy-cheeked, Boys’ Own ring to it that has – until now – been rather belied by his oeuvre, which includes a dance version of Edward Scissorhands, as well as dark retellings of all the traditional story ballets. But the New Adventure which rolled into Sadler’s Wells last night really is an adventure – an adaptation of William Golding’s Lord of the Flies, the desert island schoolboy story heavy with allegory about the propensity of human beings to descend into barbarism.}

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

In a moment of wild fantasy, I thought I might try and write a whole review of Manon without mentioning sex. After all, there’s plenty of other stuff going on in Kenneth MacMillan’s tale, which last night at the Royal Opera House celebrated 40 years since its première. Inequalities of class, wealth and power are ever present, and in fact drive the story to its sticky (quite literally) conclusion in the Louisiana swamps.

The fabulous dancers known as BalletBoyz The Talent 2014 looked so at home in the Royal Opera House’s Linbury Studio Theatre last night that it was hard to believe they had never performed there before. The BalletBoyz themselves, Michael Nunn and Billy Trevitt, were Royal Ballet leading men back in the day, and they have been back to Covent Garden since leaving in 1999 to explore new avenues in contemporary ballet for men, but this was the first time that their new company of young dancers (now 10-strong) had been invited into the inner sanctum of British ballet.
