JThis year’s Proms have been accompanied by an unusual choral drone, a monotony of voices whinging about the prodigious heat at the Albert Hall. For one night only no one was complaining as the temperature gauge went up to something like 111. You’ve heard of the Hollywood Prom and Comedy Prom, the Gospel Prom and the Dalek Prom. As a troupe of classical Spanish dancers swished and swirled, stomped, strutted and thrust to pulsating Hispanic music, here was something never before seen: the Erotica Prom.

Are we seeing a breakdown in the ballet company system? Where the brightest stars used to twinkle in the great companies, all is changing. Alina Cojocaru, the great Royal Ballet ballerina, has announced today she's joining English National Ballet - run by another great Royal Ballet ballerina, Tamara Rojo. For ENB to have the two finest talents of the past decade in Covent Garden now at the head of their cast lists is the biggest stunner since… well, since the Bolshoi Ballet's young superstars Natalia Osipova and Ivan Vasiliev quit to join the smaller Mikhailovsky Ballet.

Happy truisms first: Paco Peña is still the greatest of flamenco guitarists, he works with a consummate team of regulars in the most vibrant of dance-art and he keeps it fresh by scouring the world for different players or ensembles to complement his own flamencistas. I’ll never forget equal artists Venezuelan Diego Alvarez, creating miracles from the simple plywood box with vibrating strings known as the cajón, and on this occasion the breathtaking Senegalese dancer Alboury Dabo.

When a person is happy in his work, he does his best. So best ignore what Sergei Polunin says on the page of a newspaper and look at what he does on stage. Now there’s a happy boy. Polunin is the one reason to see the Stanislavsky Ballet at the Coliseum on this short visit, though it's always a pleasure to hear Delibes’s divine score to which Roland Petit created a short, pert, thin and very French version of Coppélia, chockful with kisses.

Just a fortnight before Russia's great Bolshoi Ballet lands in London for its splendid summer tour, it has now added a lost chief executive to its tally of a blinded ballet director, an arrested dancer, and a sacked star.

A stage performance in any art form communicates through sound and motion. A photographer's task is to capture the dramatic experience in the silence and stillness of the 2D image. In the worlds of ballet and opera, none does it with more commitment to truth and drama than the great Laurie Lewis. To mark the end of the 2012-13 season, we present 25 images selected by the photographer exclusively for theartsdesk.

In a summer awash with Russian ballet, at its best extravagant, limpid, spectacular - an experience of emotions processed through the eyes - a visit by an American company comes from a quite different sensory position: dance as intelligent motion, rhythmically schooled athleticism. While the American ballet was generated by a grandly classical Russian, George Balanchine, one of the things your eyes constantly search for in watching a US company is the way the Russian ballet genes, nurtured in Tsarist palaces, mutated when they met the bold, open-air, workaday grace over the Atlantic.

Technology and dance have long been ardent bedfellows. No other theatrical art gobbles up illusions and tricks quite as greedily and spits them out quite as intriguingly altered. Gaslight was a new technology without which the romantic ballets Giselle and La Sylphide could not have existed. Without electric light such exotic adventures in sunshine as Le Corsaire or Don Quixote could not have partied over the late 19th-century St Petersburg stage.

William Forsythe and Anne Teresa de Keersmaeker in a week - it has to be Sadler’s Wells, the theatre to sample some of the world’s best dance stuff. De Keersmaeker’s Rosas are briefly here to take part in Sadler’s "Sampled", a new thread of summer performances surrounding a single famous piece with chat, film, interactivity and other related things.

My great-grandmother used to say, "In the fall, leaves fall," meaning that as the weather gets colder, people die. The Royal Ballet has had leaves falling all year, and in the height of the (ha!) summer one of the most tenacious, and most beautiful, finally fluttered down. Leanne Benjamin, a principal since 1993, retired in the role of her choosing, Kenneth MacMillan’s Mary Vetsera, a crazed, sexed-up nymphet with a death-wish.
