So much pressure is on for Lise Davidsen to be the next Kirsten Flagstad or Birgit Nilsson, but the question has to be asked: is this just The Voice - a big "just" when a dramatic Wagnerian soprano is at stake - or The Complete Artist?

Where to begin with the most appropriated musician in history? The Barbican’s Beethoven 250 celebrations got off to an auspicious start with a weekend of events, styled like a pop festival, which nonetheless put the composer back where he belonged – in Vienna, at the turn of the 18th century – and set fire to some tenacious myths.

"Citizen. European. Pianist," declares Russian-born, Berlin-based Igor Levit on the front page of his website. One should add, since he wouldn't, Mensch and master of giants. High-level human integrity seems a given when great pianists essay epics: certainly true of Elisabeth Leonskaja and Imogen Cooper tackling respective sonata trilogies by Beethoven and Schubert, or András Schiff in Bach's Well-Tempered Klavier. Last night was on that level.

Jukka-Pekka Saraste doesn’t visit London much these days. He was Principal Guest Conductor of the BBC Symphony Orchestra, and there were rumours that he was in line for the top job. That didn’t happen, and his career soon took him elsewhere – which was a great shame if last night's evening’s Shostakovich was anything to go by.

Not long after noon on Sunday, strange bells began ringing. In just 11 bars, Bach summons pairs of flutes, oboes and violas da gamba against pizzicato strings and continuo to tintinnabulate against the alto's recitative lines about a "vibrating clang" to "pierce our marrows and our veins". These hallucinatory sounds and harmonies could have been composed yesterday. Instead they're at the service of a 1727 lamentation mourning the death of a princess.

#Beethoven250 is in full swing at the Barbican. Like most venues, they are keen to show a different side to the composer in his jubilee year. And the oratorio Christ on the Mount of Olives ticks all sorts of anniversary boxes.

Why go to hear a cello-and-piano recital in a large hall, and a rather unsatisfying programme (delayed without explanation for 15 minutes, incidentally) spotlighting a transcription of a work which was created for the violin?

We’re touring across Europe in January 2020, visiting five countries to perform eight concerts with the world-class violinist Maxim Vengerov as our leading soloist. The tour has been organized by the European Foundation for Support of Culture.

As Artistic Director and Principal Conductor of the Armenian State Symphony Orchestra, I’ve always sought to combine the eastern and western musical traditions together when programming concerts for the orchestra, whilst also presenting new music to audiences.

You can see the temptation.

Alina Ibragimova’s solo journey (in 2015) through the peaks and abysses of Bach’s Sonatas and Partitas gave me vivid Proms memories to treasure for a lifetime. The Russian-born violinist’s Bach abounds in both majesty and tenderness, as well as a consuming fire of intensity when the music so demands. She brought something of the same quality to her performance last night of Mendelssohn’s E minor concerto at the Barbican.
