Mariam Batsashvili, the young virtuosa pianist from Georgia, is a star. No doubt about that. Trained at the Liszt Academy in Weimar and winner of the International Franz Liszt Competition for Young Pianists in that city in 2015, she should know something about how to play Liszt’s music.

Last night was the first time I had heard the 12 Ensemble, a string group currently Artist-in-Residence at the Wigmore Hall, and I was very impressed, both by the standard of the playing and the enterprising programming. This gave regular audience-members a little of what they’re used to (a chunk of Brahms) and a decent portion of what they’re not.

Serious realisation of the seven often thorny Martinů string quartets is a major undertaking. When I spoke to Veronika Jarůšková and Peter Jarůšek after an East Neuk Festival concert, they said they intended to do it slowly, with absolute commitment. Tuesday night’s performance of the stupendous Fifth sealed the pledge. It held central place in a concert which only brought relief from Czech grittiness with the great cathartic melodies in Brahms’s Third Piano Quartet.

The BBC Philharmonic were right to bill Garrick Ohlsson, soloist in Brahms’ Piano Concerto No. 1, as the main attraction in Saturday’s concert.

The septuagenarian American is a force of nature and an exceptional artist: his playing of Rachmaninov in his last visit to Manchester remains in the memory as an exhibition of mastery. So it was again, in another concerto thick with notes.

Last Monday my colleague Boyd Tonkin was delighted by the Kaleidoscope Chamber Collective’s playing at Hatfield House – and on Thursday it was my turn to be impressed by their colourful Wigmore Hall recital, which featured the marvellous clarinettist Carlos Ferreira in Bartók and Brahms.

Christian Gerhaher, the most compelling and complete interpreter of German Lieder of our time, makes no secret of the fact that – unlike his devotion to, say, Schumann – his relationship with the songs of Brahms has never been comfortable.

Founded by Daniel Barenboim and Edward Said, the West-Eastern Divan Orchestra first performed at the Proms – to a rapturous welcome – in 2003. For two decades the visits, and the audience rapture, have continued, while the region of most WEDO players’ birth now looks, this hideous year above all, more steeped in blood and hate than ever. 

Advice to young musicians, as given at several “how to market your career” seminars: don’t begin a biography with “one of the finest xxxs of his/her/their generation”. From my side, I’m allowed to use it occasionally: surely Timothy Ridout is the finest viola-player of his generation, and last night he struck sparks off four other artists at the top of their game: violinists Maria Włoszczowska and Tim Crawford, fellow viola-player Ting-Ru Lai and cellist Tim Posner
