With Kavakos, Faust, Shaham and Skride already been and gone, and Jansen, Ehnes, Bell and Ibragimova still to come, the LSO’s International Violin Festival has nothing left to prove. We’re not short of star power in London’s concert scene, but even by our spoilt metropolitan standards this is a pretty unarguable line-up. With excellence a given, then, it takes quite a lot to startle a crowd into delight – especially on a Sunday night. But that’s what Christian Tetzlaff did with the unassuming freshness and brilliance of his Beethoven.

Mahler once wrote that his symphonies were edifices built from the same stones, gathered in childhood. In each of the four recitals I’ve heard from Yevgeny Sudbin, he’s moved several of his repertoire cornerstones around to different effect in the piano-programme equivalents of a very large symphony orchestra playing a Mahler symphony: massive sonorities, total structural grasp, huge intelligence.

Conductor Robin Ticciati and pianist Javier Perianes are an odd couple. Ticciati is forthright and disciplined, while Perianes is reticent but erratic. But they demonstrated last night that Beethoven's Fourth Piano Concerto can accommodate those extremes, and even draw on the resulting tensions.

When the curtain came down on Liverpool’s year in the limelight as European Capital of Culture, back in 2008, there may have been some who thought that the party was over. Things in the city’s arts world were never going to the same, however, and much has changed since 2008, mostly for the better. But there is one institution which, though it’s been through some major changes in its lifetime, is a constant on the Liverpool scene.

When you’re visiting someone for the first time, it’s probably just as well that you make a good impression – or else you may not be asked back. If that’s what the Carducci String Quartet was trying to do on their début visit to Liverpool, then they did all the right things.  They mesmerised the audience with their performance of the second of Beethoven’s "Razumovsky" quartets, so much so that they were forced to sit down and perform an encore, which turned out to be a little irreverent Shostakovich, in the shape of the Rondo Polka.

Youth may have vanished from the title, and its first flush is gone from the cheeks of most of the young persons. Now they’re in their prime, a magnificent sight – and the sound, too, is that of a world-class orchestra with a voice. Which we heard at its most distinctive, deep and muscular, from the strings in the opening signals of Beethoven’s Fifth Symphony. So what went wrong with the music from Wagner’s Ring in their first 2015 Southbank concert’s second half?

Even the most reluctant of completists should find the prospect of the Beethoven works for cello and piano undaunting. In their totality, these pieces consist of just five sonatas and three sets of variations, which fit neatly on to just two CDs, or occupy two recital programmes. The works are also very important in the early development of the solo cello repertoire. Beethoven biographer Jan Swafford describes the “confident, ebullient, fresh and youthful” sonatas of Op 5 as a genre which the composer, at the time, had “virtually to himself".

This concert was part of a tour of Canada’s National Arts Centre orchestra to five cities in the UK themed around the anniversary of the start of World War One. The Ottawa-based orchestra joined forces with the Royal Philharmonic Orchestra and the London Philharmonic Choir for this London centrepiece to the tour, under the baton of violinist-turned-conductor Pinchas Zukerman.

Musical theatre needn’t be dominated by the human voice. Instrumental dramas with an element of acting can be a good way into the wonderful world of chamber music for younger audiences, and the Wigmore Hall’s new gambit of special student tickets for contemporary music paid off with the very different crowd there last night. It was rewarded with playing of the highest imaginative order from soloists in their own right: violinists Patricia Kopatchinskaja and Pekka Kuusisto, viola-player Lilli Maijala and cellist Pieter Wispelway.
