Praise be, or slava if you prefer, to Valery Gergiev for honouring new Russian music alongside his hallmark interpretations - ever evolving or dangerously volatile according to taste – of Prokofiev, Shostakovich and Stravinsky. Last LSO season featured some of the less than inspired recent works Rodion Shchedrin has been dredging by the yard. Yet few would begrudge the palm of deep and original musical thought to this past week’s heroine, Sofia Gubaidulina.

Many of Italy's artistic institutions may have tottered or crumbled during the Berlusconi years, and the more capable new man in the Palazzo Chigi can only offer painful sticking plaster, yet one major orchestra has never sounded better.

How good it feels, after several decades of Shostakovich quartet series, to be able to say not just “what a tragic life” but also “what ingenious treatment of great ideas, what a range of universal human emotions”. And even, walking on air away from the second concert in the Pacifica Quartet’s Wigmore Shostakovich cycle, “how accepting, how at one with the world”.

How can even a generously proportioned documentary do justice to one of the musical world’s greatest life forces? John Bridcut knows what to do: make sure all your interviewees have a close personal association with your chosen giant in one of his many spheres of influence, then get cellist-disciples from Rostropovich’s Class 19 in the Moscow Conservatoire – here Moray Welsh, Natalia Gutman, Karine Georgian and Elizabeth Wilson - to watch and listen to their mentor talking and playing. The result is a towering model of its kind.

In Italian opera, where lustrous Verdi mezzos are rare indeed, Olga Borodina tends to a first-the-music-then-the-words approach. In Russian song, the sole focus of last night's Barbican recital until the second encore, her classy, naturally inflected and beautifully coloured realisation of great as well as more generic native poets leaves you in no doubt what you're supposed to feel and think.

An all-Russian prom with two masterpieces centre stage and a remarkably compelling young violin artist brought in a packed house last night. Esa-Pekka Salonen and Lisa Batiashvili have already recorded Shostakovich’s First Violin Concerto, and the bond between them was evident in a delicate yet deeply searching performance of this melancholy, epic work with Salonen's orchestra, the Philharmonia.

The two-course evening out is made possible by the Wigmore Hall’s late Friday-night concerts, so if you get out of a central-London show - or dinner - by, say, 9.30, you can add a second layer of entertainment at 10. In my case, a ferociously poor hour spent at contemporary dance in Sadler’s Wells was offset by an hour with Joanna MacGregor in a stimulating splicing of Bach and Shostakovich piano music that at least offered something to think about, if not ultimate satisfaction. Evening not entirely wasted, then.

Honour your senior master conductors: there aren't so many of them left now. Abbado and Haitink spring most readily to mind, but orchestral musicians may also nominate Neeme Järvi, who celebrated his 74th birthday last week. A passionate patriot and the man his country voted "Estonian of the Century" in 2000, he proudly sports the colours of the national flag in concert attire by virtue of a natty added blue handkerchief.

It’s string-quartet Saturday – a young German group tackle Soviet classics and a rejuvenated Russian quartet smile with Haydn. There’s music from a contemporary Polish master and exquisitely uncomfortable fin-de-siècle music from Vienna.
