A voluptuous dream in sequined silver, the nearly-27-year-old Georgian pianist Khatia Buniatishvili sat down at the keyboard and instantly transcendentalised her mermaid look as Ravel’s Ondine. Even Brahms took to the life aquatic of her recital’s first half. For the second, though, there should have been a costume change into a clown suit with a tatty tutu pulled over it.

Where did all the terrific programming energy of last year’s The Rest is Noise festival go? One answer – surprising given the orchestra’s former Friday night lite status – is into a two-concert adventure by the BBCCO. World to Come, World Once Known has been devised by Principal Conductor Keith Lockhart to reflect the Janus-headed phenomenon of music just before, during and after the First World War.

This was the first of three Royal Festival Hall concerts during the first half of 2014 from the Royal Philharmonic Orchestra and its principal conductor Charles Dutoit, all three programmes consisting entirely of French music. The other two will be in May. In between the Swiss-born conductor, a sprightly 77-year-old, will have picked up a Lifetime Achievement gong at the International Classical Music Awards in Warsaw.

Among the diaspora of younger-generation Russian or Russian-trained pianists, there are at least four whose intellect and poetry match their technique. Three whose craft was honed at the Moscow or St Petersburg Conservatories – Yevgeny Sudbin, Alexander Melnikov and the inexplicably less well-feted Rustem Hayroudinoff – have made England their home. Boris Giltburg - the youngest of the group with a fifth, Denis Kozhukhin, close on his heels - left Moscow for Tel Aviv when he was a child and has had a different training.

French-Canadian pianist Hamelin has the technique and the stamina to play anything, which is why the note-crazy, obsessive “Night Wind” Sonata of Nikolay Medtner buzzed around at the heart of his recital. But between the proud resonance of its many climaxes and the distant voices he showcased so effectively in his own Barcarolle – three movements rather than one, unexplained in a note which simply ignored it – there’s little delicacy in the middle ground.

Back at the Barbican for a new season after a Far Eastern tour, the BBC Symphony Orchestra returned to pull off a characteristic stunt, a generous four-work programme featuring at least one piece surely no-one in the audience woud have heard live before. This time, the first quarter belonged exclusively to the unaccompanied BBC Singers in one of the most demanding sets of the choral repertoire. After which the seemingly humble but dogged and vivacious Marc Minkowski helped create orchestral magic of three very different kinds, defining French composers’ infinite capacity for play.

The visits of the Gustav Mahler Jugendorchester are a regular Proms highlight, only preceded (for me) by the John Wilson Orchestra in the speed with which they go from announcement to diary. Last year’s concert under Gatti was a whirling celebration of dance – a beautifully programmed narrative that spun us from Wagner to Ravel and left us breathless. The year before Tchaikovsky and Rimsky-Korsakov brought us passions from East and West, united by the precision of Sir Colin Davis.

On most of her London visits, Elisabeth Leonskaja has been an unassuming high priestess of the mysteries and depths in core sonatas by Beethoven, Chopin and Schubert. This time she applied her Russian-school style of orchestral pianism, tempered as always by absolute clarity, to burning the mists off Ravel, Debussy and the French-inspired Romanian, Enescu. She went on to give us colossal enlightenment in what must be the greatest work ever composed by a 19-year-old, Brahms’s Third Piano Sonata in F minor.
