“Take Jazz Seriously,” wrote Maurice Ravel after his American trip in 1928. This past week of the 2021 EFG London Jazz Festival has seen that advice itself being taken seriously, with a bunching of projects and premieres. Jazz musicians have been welcomed in to work with London orchestras. The fruition of months of preparatory work has been on show.

Where do you draw – how do you draw? – a credible line between jazz and “classical” music in 20th-century America? With the reliably boundary-busting Britten Sinfonia, trumpeter Alison Balsom mixed and matched works from different formal lineages in her packed programme at Milton Court, “An American Rhapsody”.

The world of the 17^th-century tavern is a long way from the contemporary concert hall. A quick glance at the scene in paintings by Jan Steen or his contemporaries shows us a joyful tangle of men and women, dogs, cats and small children, all engaged in a riot of drinking, dancing, brawling, music-making and love-making (occasionally even napping) while hens stroll officiously across the floor pecking up crumbs. It looks noisy, dirty and a jolly good time.

Comparisons might have been odious between three of the world's most cultured players – pianist Jitka Cechová, violinist Jan Talich and cellist Jan Páleníček of the Smetana Trio – and the young, British-based Minerva Piano Trio (Annie Yim, Michal Ćwiżewicz and Richard Birchall).

Sometimes you know the quality of music by the depth of the silence when it ends. Last night at Middle Temple Hall – and thank Mahler’s mystical heavens for it – the final ghostly “Ewig” of Der Abschied faded away into a soundless void that lasted just as long as it had to.

The Takács Quartet is hard to pin down. The group was founded in 1975 in Budapest, but since 1983 has been based in Boulder, Colorado. Cellist András Fejér is the only remaining founding member, and the violist, Richard O’Neill, only joined in 2020. They also have a British first violin, Edward Dusinberre. So what performing tradition can we expect from them?

Who will write the world’s first eco-concerto? Tom Coult, with his major debut piece for the BBC Philharmonic since becoming its Composer in Association, a violin concerto titled Pleasure Garden, has made his bid.

One benefit of the green tide in culture – music included – is that it should allow audiences to approach the arts inspired by the natural world in Britain, and elsewhere, a century ago with fresh ears and eyes. Weary over-familiarity can render a work such as Vaughan Williams’s The Lark Ascending virtually inaudible, just as much as neglect.

Where is the stage – outside or within? The question posed by the prologue of Bartók’s only opera addresses the fundamental privacy of our thoughts, as well as setting the scene for its drama within the theatre of our own minds. For many of us a year and a half of periodic lockdown has only turned up the volume on the echoing contents of our heads, lending an unlooked-for familiarity to Bluebeard’s forbidding castle.

Welcome back Andrew Litton, Conductor Laureate of the Bournemouth Symphony, for the latest of many happy annual returns since his tenure as Principal Conductor between 1988 and 1994.
