If Dr Frankenstein wanted to manufacture the perfect violinist, he’d require a long list of ingredients. Perfect, unfussy technique, of course; but also seriousness of purpose, a sense of humour, a clear head, a passionate heart, a generous tone, plus access to a Stradivarius. On the other hand, the good doctor could simply go out and find Julia Fischer, the 28-year-old German violinist who ticks almost all of the above boxes, except perhaps “sense of humour”.

Hurry! Hurry! Hurry! Only the last umpteen hours left of BBC Radio 3’s The Spirit of Schubert marathon. After some 200 hours of broadcasting to mark the 215^th anniversary of his birth, Franz can perhaps be left to rest easy for a while. The poor chap has been scrutinised, analysed and turned inside out this week.

In this, the work’s 50^th anniversary year, there will be a lot of War Requiems. Benjamin Britten’s howl of Pacifist conviction has lost little of its poignancy since its composition – a period marked by the almost continuous military presence of British forces abroad. With action in Afghanistan coming to a close and political stirrings animating the Falklands issue once again, this plaintive reminder of “truth untold”, of the “pity of war” still speaks loudly and directly.

Originally, this concert was to open with that mercurial wonder Martha Argerich playing an unspecified piano concerto. Then its first item became Martha Argerich not playing anything, for the good lady, almost as rare a visitor to Britain as the Man in the Moon, did what she’s famous for doing. She cancelled. Acting with award-winning panache, the Barbican then found a substitute artist who’s recently become even rarer, the violinist Maxim Vengerov. 

I don't much like aspirational music-making. I like my classical classical and my pop pop. Give me Boulez over Bernstein, Britney over Radiohead, any day. Having said that, I'd heard a piece by Jonny Greenwood at Reverb last month that had gone some way to winning me over. For a brief moment, Greenwood dropped the avant-garde pose that he's adopted for most of his other classical compositions and indulged in a bit of tender-hearted Romanticism that was nothing if not charming. This kind of honesty was not much in evidence in his team up with Penderecki last night at the Barbican. 

There was a lovely narrative to last night's CBSO concert. The muggy oppressiveness of Britten's Four Sea Interludes (and Passacaglia) appeared somehow explained by Mahler's Kindertotenlieder, then dissolved by the love letters that were the Strauss songs and then finally set free - psychologically and orchestrally - in Debussy's La Mer. Parallel to this, the great German tenor Jonas Kaufmann was being washed out to sea; his Mahler and Strauss songs were being lapped at from both directions by Debussy and Britten's portraits of the salty waters. 

Their bicentennial years may have been and gone, but even Mazeppa’s wild horse wouldn’t be able to stop the world’s top pianists playing Chopin and Liszt almost every month. Last night Maurizio Pollini and his aristocratic art returned to the Royal Festival Hall for a recital featuring both composers, each on either side of the interval. Pollini also brought his Steinway-Fabbrini touring piano – a Steinway from the Hamburg factory, titivated inside with extra refinements by the piano technician Angelo Fabbrini.

It's often more fun on the margins. The pickings are richer. The view is clearer. You can take aim easier. The AV Festival has spent more than eight years here, on the counter-cultural edges, delving into the divisional cracks between art, music and film.

For more than 10 years now I have been waiting in vain for the pianist Evgeny Kissin to shatter the stereotyped image built around him by music critics who haven’t always liked what they’ve heard. You know the kind of thing: Kissin the visitor from outer space, the strange performer who bows to the audience like a priest at a religious rite, displays plenty of peerless technique, but after decades cocooned and fêted on the virtuoso circuit appears too often emotionally remote, as if his feelings had been locked in his dressing-room fridge or maybe a strongbox in Siberia.

There’s always a bit of a buzz around a premiere, even one which may seem slightly off-the-wall. Jan Sandström’s Echoes of Eternity is a concerto for two solo trombones – unusual in itself, given that there are precious few concerti for just one solo trombone – and symphony orchestra. Add to that the fact that one of the soloists is also the conductor and it’s easy to see that this piece is beginning to get complicated.
