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.

Out of emergencies may come revelations. Sir András Schiff has broken his leg, and we wish him a super-speedy recovery. At the Proms, his promised Art of Fugue will have to wait. Korean pianist Seong-Jin Cho, a past winner of the Chopin Prize, stepped in yesterday with a late-night recital programme that at first glance could hardly have looked more alien to the austere grandeur of Bach’s contrapuntal epic.

The summer festival circuit in Central Europe can be a bit of a merry-go-round. Notices in festival towns promise world-class orchestras and soloists, but they are usually the same performers, making festival appearances as part of broader touring schedules.

For a small nation, with a population not quite comparable to Scotland’s, Georgia has for long packed a mighty musical punch. Any visitor will know the soul-wrenching power of its choral polyphony, but a post-Soviet generation of classical soloists now walks proudly across the world stage. Pianist Mariam Batsashvili, only just 30, won the Franz Liszt international competition in 2014 and has since been a BBC New Generation artist.

The Edinburgh International Festival’s Queen’s Hall series ended with two very impressive debuts. Thursday morning brought the Isidore Quartet, who winningly, if slightly naively, told us that Edinburgh had a similar energy to their native New York.

Conductor and pianist came at Liszt from opposite directions last night. Michael Tilson Thomas is a venerable presence at the podium and has been Laureate Conductor of the London Symphony for decades. Their relationship speaks of deep empathy and close communication. In the Liszt First Piano Concerto, MTT dug deep into the rich string tone of the LSO for round, warm sonorities, and always with plenty of bass.  

“O wise young judge”, says Shylock to Portia in The Merchant of Venice.It seemed just such a figure who made her way to the piano at the Wigmore Hall last night. Besuited, bespectacled, with a poised upright posture that frees her arms, plus the serious demeanour that I sometimes term “Heifetz face”, the youthful Georgian pianist Mariam Batsashvili eschews any fashionable emoting, arm-flinging or face-pulling.

It can be found in any contract. Both artists, as well as promoters, are aware of it, but it used to be an exception so rare that only a few have ever experienced it: the clause of "force majeure". Now it is sadly commonplace in the world of the performing arts.
