L’Orchestre du Nouveau Monde’s young musicians went viral for their defiant performances during the last week’s protests in France. They belong to a fine tradition of radical orchestras. Also, today, what music should soundtrack the Traitors?

They were the last people standing – or rather playing – during last week’s student protests in France, as gas canisters landed in double-bass cases. L’Orchestre du Nouveau Monde, co-founded by young conductor Étienne Jarrier and his friends when they were still teenagers, aren’t a typical orchestra. With their manifesto of activism and social justice, the orchestra is not “a sacred object of beauty, but a tool for struggle”, through civil disobedience, outreach in schools, demonstrations and concerts, all to “present a different kind of classical music – one reconnected to reality”.

The new world Jarrier and his group dream of is “anti-racist, anti-capitalist, feminist, environmentalist and committed to de-growth”, and their way of working is deliberately provocative, not only to so many of the dominant directions of travel in the political world, but also to the institutions of classical music. They play scrappily passionate performances of La Marseillaise, of music from The Avengers, of Dvořák’s New World Symphony and protest songs but the ONM judge the quality of their performances not by playing the right notes in the right order, but by their consciousness-raising impact, whether they’re staging performances at Place de la République in Paris or at the foot of a glacier.

The death of Stephen Kovacevich, aged 86, was announced yesterday. Tom Service pays tribute to a pianist whose performances were full of beauty, clarity – and danger

And, here, in a piece published on Kovacevich’s 75th birthday, Andrew Clements picks his favourite recordings.

It was just a couple of weeks ago that Stephen Kovacevich and I were last in contact. He was in hospital, recovering from a hip operation, and we were talking about Hiromi, and where the latest generation of pianists were coming from. The players who had the brilliance, fire and commitment to the moment that his favourite players had: Vladimir Horowitz, Sergei Rachmaninov – his greatest of the greats – and his friend and occasional mentee, Yuja Wang.

Among other things, he told me about a Charles Munch performance of Berlioz’s Symphonie Fantastique he had discovered on YouTube that made him exclaim: “How the hell did he get an orchestra to play like that?” Conversation with Stephen was always like that: utterly intense, totally opinionated, with the feeling that the spirits he was talking about, whether performers or composers from Chopin to Beethoven to Brahms to Mozart to Bach, were in the room with you, conjured into being as real, passionate people and presences.
