Carlos Acosta is that rare 21st-century phenomenon – a performer who has become a household name without the help of reality TV. Even people who run a mile from ballet know the story of the Havana slum boy made good through perseverance and pure talent, from countless primetime documentaries as well as a self-penned book and stage show. The Royal Ballet cannot have imagined how things would turn out when it signed its first (and, to date, only) black principal 17 years ago.

Swan Lakes are not created equal. In fact they are not even created the same: ballet is the art form with the evanescent repertoire, in which First Folios – or any folios – are singularly scarce. Even with a classic as beloved as Swan Lake, there is no stable text apart from Ivanov's lakeside choreography for Act II and Tchaikovsky's score (though not even all of that).

If you’re going to employ tens of extra musicians for Strauss’s gigantic Alpine Symphony, it’s probably just as well that a few other "biggies" are programmed in the same concert. So it was at the Philharmonic Hall, where the Strauss shared the programme with a new orchestration of Tchaikovsky’s The Seasons as well as a selection of Canteloube’s haunting Songs of the Auvergne. All three pieces are evocations of a place or a season, so this whole concert was almost a musical novel or an orchestrated visit to an art gallery.

If you don’t know the steps or the stars being semi-spoofed, will you laugh? Yes, though perhaps not as much as anticipated. The best parody needs to be as good as the original, and “the Trocks”, as Tory Dobrin's New York-based company has been known in its 40-plus years to date, take their Petipa and Ivanov very seriously. The drag gags are mere ornaments to a classical feast, and don’t fly into the fantastical like some of the ones you get in any Matthew Bourne show; the real reward is some remarkable dancing.

Russian classics evening at the Proms? It could be what Alexandra Coghlan, writing about Prom 69, described as “another night at the musical office”. But given the masters in charge of two masterpieces fusing storytelling with symphonic sweep and one deservedly popular standard, there was no chance of that. Nikolai Lugansky is the only pianist I’d go out of my way to hear live in Rachmaninov’s Second Concerto, and while Yuri Temirkanov’s programmes with the St Petersburg Philharmonic have been pickled in aspic for years, their music-making together certainly hasn’t.

St Petersburg Ballet Theatre is a phenomenon of the new Russia: not anchored in centuries of history or state patronage like its neighbours the Mariinsky and the Mikhailovsky, but founded as a commercial venture in 1994 by Konstantin Tachkin, a wannabe impresario with no balletic training. It tours widely, and evidently has no difficulty selling out foreign theatres – including the Coliseum for Swan Lake last night – with a combination of recognisable productions and "Russian ballet" cachet.

In 1989 Neeme Järvi, already rated one of the world’s top conductors and soon to be voted “Estonian of the Century” by his compatriots, returned with his Gothenburg Symphony Orchestra to the homeland he had left for America nearly a decade earlier. I went with them then, and to experience a free Estonia 26 years later was a bracing surprise.

Last week the 15th International Tchaikovsky Competition in Moscow was rung down with a sigh of relief for the home team, with once again a Russian pianist in possession of the gold medal, Dmitry Masleev following 2011’s Daniil Trifonov. It was all very satisfactory for President Putin as he delivered his speech at the winners’ gala, being Tchaikovsky’s 175th anniversary year, but it was not a result that many disputed. The modest Siberian, 27, is a thoughtful pianist as well as a powerful one in traditional Russian manner.

Medtner: Piano Sonatas Alessandro Taverna (Somm)

The delicacy of its supernatural elements make Pushkin’s The Queen of Spades, as adapted by Tchaikovsky, a tricky proposition for any director. Do you go with the ghost story and risk losing your audience emotionally, or do you play it straight, trying to rationalise the plot’s moments of macabre? The hands of the clock stand perpetually arrested just moments before midnight in David Alden’s new production for ENO, putting his audience out of any doubt as to which he has chosen.
