Even that most unpredictable of fantasists Nikolay Gogol might have been surprised to find his Nose, wandering far from the face of Collegiate Assessor Kovalyov, sung by a high tenor in an unlikely operatic adaptation of his wackiest story. Give the singing role, as Barrie Kosky does, to another character, and show the giant-sized Nose – here a boy dancer – without any token apparel of his supposed high rank before which lowly official Kovalov absurdly grovels, and you miss the point of a vintage scene in Shostakovich's The Nose.

With a trio of easy-on-the-ear 20th-century works, Thomas Søndergård marked his debut with the London Philharmonic Orchestra. A pleasingly full crowd took the opportunity to hear the work of a conductor rarely glimpsed in these parts outside the BBC Proms. His appearances there in charge of the BBC National Orchestra of Wales have given the impression of a contented, highly competent musician, at ease both with the players before him and the scores on the music stand.

He still looks every inch the golden boy, but Vasily Petrenko has just turned 40, and next month celebrates a decade with the Royal Liverpool Philharmonic. Time well spent, as this impressive evening revealed: after years of Russian immersion under his crisp command, here’s a band who can conjure Shostakovich’s smoudering darkness, and all the glitter and the grit in Rachmaninov’s third symphony.

What do women want? Ballet plots are not the best guide, since the main desiderata – a well-paying job, coffee dates with girlfriends, not to die young of a broken heart – are rarely the lot of ballet heroines. Comedies at least tend to have the not-dying part covered, but they often fall down on at least one of two other big requirements: that one's family should be supportive, and that one's romantic partner should not be a chump.

Flashback to 1981, when the Bolshoy Ballet danced Swan Lake Act Two to a tinny Melodiya recording in Istanbul's Open-Air Theatre (seats were cheap for Interrailing students). Turkey was friends with the Soviet Union then. It hadn't been in the 1950s, when Turkish pianist and citoyenne du monde İdil Biret was advised not to play a Prokofiev sonata in her motherland.

If you needed further proof of the intelligence, the thoughtfulness of Daniil Trifonov’s musicianship, the programme for his four-concert residency at the Wigmore Hall would go a long way towards providing it. How many young soloists of Trifonov’s standing would choose to turn song-accompanist for an evening of lieder? And how many, having done so, would deliver so generous and self-effacing a performance?

Behemoth Dances. Who dances? You know, Behemoth, the huge demonic black cat who cakewalks through Stalin’s Moscow in Bulgakov’s The Master and Margarita spreading mayhem and magic; the spirit – as quoted by Bulgakov, and taken by Stephen Johnson as a sort of motto for his new orchestral work – “that always wills evil, but always does good”. A sardonic fanfare announces his appearance, before the orchestra whizzes away on a bustling, bristling spree. Woodwinds squeal and skirl, the surface glitters, and a piano throws in a few deadpan comments.

What makes a musical performance? The final of Young Musician 2016 presented five judges with this philosophical teaser to ponder. For the previous 90 minutes three contestants with three radically contrasting styles of delivery cleared every bar in front of them, with the help of Mark Wigglesworth and the BBC Symphony Orchestra. Giving the nod to one meant the elbow for the others.

Cherrypicking from 17 concerts to come up with the one by last year's Leeds International Piano Competition winner may seem a bit unfair to the French Institute's ever more ambitious annual It's All About Piano! Festival. It was hard, for instance, to miss out on the youth element, the Satie bookending the weekend's events, or for that matter the absolute star of the festival two years ago, David Kadouch, who then gave one of the best, and most intriguingly programmed, recitals I've ever heard and teamed up for a Saturday night duo recital with Adam Laloum.

Funny thing, musical fashion. Most listeners would call Borodin’s Polovtsian Dances a popular classic – yet before tonight, I doubt they’d had a professional performance in Birmingham this century. Then there’s the case of Osvaldo Golijov. Remember him? The very fact that it’s taken 10 years for a work as substantial and appealing as his cello concerto Azul to receive this UK premiere tells you all you need to know about how far his stock has fallen – at least for now.
