The penultimate concert in the eclectic and impressive K-Music Festival of contemporary Korean music on Monday at the Purcell Room featured some of the most exquisite and affecting performances of the season, with the traditional Gayageum stringed instrument paired with an effects-laden, ambient-cum-exploratory jazz quartet featuring one of the most distinctive and arresting drummers anywhere, making remarkable music from her kit (shimmering cymbal solos, anyone?).

How many times have you heard live in concert a concerto for string quartet and instrumental ensemble? In my case, three, all of the occasions performances of John Adams's Beethoven-based giant scherzo Absolute Jest.

Lightness and gravity in perfect equilibrium have always graced Vladimir Jurowski's Stravinsky.

The young Dublin folk trio fuse vocal harmonies with superb acoustic musicianship, primarily on cello, fiddle and Nyckelharpa. They bring together Irish and Nordic – specifically Finnish – folk traditions, building them to dizzying heights on a foundation of acoustic drones and group interplay.

Latvia is fighting fit. The recent elections did not see the expected victory for the pro-Kremlin Harmony party; support for the European Union and NATO will be well represented. Last week the feisty Lavtian Ambassador to the UK, Baiba Braže, landed a perfectly diplomatic punch on the smug mug of our latest apology for a Foreign Secretary, taking former Remainer Hunt to task for his outrageous parallels between the EU and the Soviet gulag by reminding him how Latvia had suffered under the USSR and how eagerly it has adopted the best European values.

During his quarter-century in charge of the Gewandhausorchester in Leipzig, the late Kurt Masur nobly held out a musical hand of friendship and collaboration from the other side of the Iron Curtain.

Not all composers require the finger of mortality pointing at them to develop what becomes a late style. Charges of detachment and even indifference have been levelled at the B flat major Piano Concerto K595 which Mozart completed early in the year of his death, but Mitsuko Uchida’s playing of it on Saturday night was as refined, as weightless and translucent as her trademark silk tops.

In an era marked by virtue-signalling, it's perhaps no surprise that Isabelle Huppert – a woman who has always gone against the grain – has opted for a little vice-signalling.

You can always be sure of impeccable casting and spirited playing as Ian Page takes his Classical Opera through Mozart year by year. Just don't expect more than the glimmer of genius to come in 1768, though. It doesn't matter in those admirable showcase programmes highlighting the young Amadeus alongside more mature voices of the year in question.

Questions of interpretation apart, Simon Rattle has yet again proved the great connecter, this time in concerts separated by just over a month.
