Why play a very substantial act of ballet music in concert? In the case of Aurora’s wedding entertainment from Tchaikovsky’s The Sleeping Beauty, there are at least three good reasons. It embraces the most inventive and unorthodox of divertissements in any ballet – the one in The Nutcracker comes a close second – and a symphony orchestra deserves the chance to perform at least a substantial chunk of what Stravinsky called Tchaikovsky’s chef d’oeuvre.

In 1986, the Russian state honoured Mikael Tariverdiev with the People's Artist of Russia award, a mark of respect given to only the most significant figures in the arts. The Tbilisi-born composer was the head of the Composer’s Guild of the Soviet Cinematographer’s Union and had written concertos, operas, ballet music, song cycles (Russian poetry was a favourite), music for television and for 132 films. He was prolific, saw few boundaries and, in 1956, had set Shakespeare sonnets to music. The following year, he did the same for Japanese poetry.

The great Bolshoi ballerina Ludmila Semenyaka once told me that you need the claws of a tiger and the hide of a rhinoceros to survive at Moscow's iconic theatre. Her bitter words came to mind yesterday morning when I saw the Twitter feed of the Bolshoi Theatre blithely congratulating the ballet artistic director Sergei Filin on his 45th birthday – along with a photo of him from before the acid attack that ruined his youthful looks, his eyesight and his career as a ballet director.

There’s a screen quotation late in this remarkable documentary that reads, “An outstanding athlete cannot belong totally to himself.” The words are those of Soviet ice hockey trainer Anatoly Tarasov, who's one of the presences behind this story of the sport seen through the eyes and experience of the legendary defender Vyacheslav (Slava) Fetisov. But director Gabe Polsky has made a broader film, one which touches on the uncertain journey Russia has undergone over the last three decades.

It’s easier to admire than enjoy 2013's Hard to Be a God. The 177-minute final film directed by Leningrad-born Alexei German depicts medieval squalor and butchery so intensely that the viewer is forced to shrink from its portrait of life without culture, humanism, and soap. Like another protracted masterpiece, Béla Tarr’s 2011 The Turin Horse, German’s miasmic swansong imparts its riches mostly after being endured and reflected upon.

“The music quacks, hoots, pants and gasps”: whichever of his Pravda scribes Stalin commandeered to demolish Shostakovich’s “tragedy-satire” in January 1936, two years into its wildly successful stage history, didn’t mean that as a compliment, but it defines one extreme of the ENO Orchestra’s stupendous playing under its new Music Director Mark Wigglesworth. On the other hand there are also heartbreaking tenderness, terrifying whispers and aching sensuousness.

The repercussions of the revelations about intelligence gathering by American and other surveillance services made by US whistleblower Edward Snowden have proved huge. Laura Poitras’s documentary CitizenFour is no less revelatory about the process of their appearance, about just how Snowden came to be in that Hong Kong hotel room with reporter Glenn Greenwald, and what happened there.

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.

The TV series on which Guy Ritchie has based his new spy-buddies movie first appeared on the small screen (in black and white) in 1964, when Napoleon Solo and Illya Kuryakin welcomed us into their secret lair in New York and introduced themselves as "enforcement agents" for U.N.C.L.E., apparently a sort of UN/CIA hybrid. The grandfatherly Mr Alexander Waverly, resembling a retired bank manager in venerable tweed, announced himself as their boss.

Iris DeMent’s settings of poems by the great 20^th century poet Anna Akhmatova are as original as they are courageous: it's so easy to fall short of the genius displayed by the Russian mistress of the lyric verse. This is a work of love and devotion – prompted in part by DeMent’s adoption, along with her partner the equally original and talented Greg Brown, of a girl from the former Soviet Union.
