Launched into an already crowded choral scene in 2016, the professional choir Sonoro has marked its second birthday with the release of a debut CD. Last night was the launch concert, featuring items selected from the disc. On the evidence of both CD and concert Sonoro is a very welcome new addition to the roster of excellent London choirs, with its own distinct sound and ethos.

Just over a year since his Bridgewater Hall début, Ben Gernon appeared with the BBC Philharmonic there again – this time well into his role as their Principal Guest Conductor, yet his first concert with them there since officially taking up the position.

The London Philharmonic, conductor Vasily Petrenko and cellist Andreas Brantelid are just back from a tour of China, so they’ve had plenty of time to get to know each other. That affinity is apparent in the ease with which Petrenko (pictured below by Chris Christodoulou) marshals the orchestral forces, directly transmitting his trademark energy to every section.

This was an evening of silence and shadow, a chill, moonlit meditation, where each sound demanded forensic attention. Enter the world of Luigi Nono and his admirers.

Schubert’s winter wanderer had Wilhelm Muller to voice his despair, while Schumann’s poet-in-love had Heinrich Heine. The lovers of Hugo Wolf’s Italienisches Liederbuch must make do with only the words of anonymous Italian authors, albeit dressed up for the salon in elegant German translations by Paul Heyse.

The Czech Philharmonic on tour are a familiar sight, and they have built a following appreciative of their particular qualities, since they are an orchestra with a sound of their own – the way European orchestras used to be, in some respects. A distinguished colleague used to call them the bouncing Czechs: I like to think they are like the best of their homeland’s beer: rich, mellow, and full of character and body.

The last time Theatre of Voices performed Stockhausen’s STIMMUNG in London was at the Albert Hall, at a late night Prom in 2008, so Kings Place made for a much more intimate setting. In fact, the work, which is for six unaccompanied voices, relies heavily on electronic amplification, so can be adapted to almost any environment. And Kings Place proved perfect, with its sympathetic acoustic and hi-tech audio array.

They were billed as a Trio, but when the classical super-group of Janine Jansen, Mischa Maisky and Martha Argerich came together at the Barbican last night it was in a sequence of different combinations, each with their own musical identity. The centre of gravity, however, remained constant. Martha Argerich, the only performer present throughout, may have reinvented herself and her sound fifty times in the course of the evening, now asserting, now effacing, but it was she who rooted the whole, who provided the fixed compass point around which her colleagues roamed so freely.

"You have to start somewhere," Debussy is reported to have said at the 1910 premiere of The Firebird. Which, at least, is a very good "somewhere" for Stravinsky, shot through with flashes of the personality to come. The Symphony in E flat of two years earlier, however, is little more than a theme park of all the ingredients amassed in Russian music since Glinka forged its identity less than a century earlier.

You can't have too much Dvořák in a single evening, at least not when the works in question operate at the highest level of volatility and melodic abundance like last night's overture, concerto and symphony.
