Medieval to Modern – Jeremy Denk’s Wigmore Hall recital took us on a whistle-stop tour of Western music, beginning with Machaut in the mid-14th century and ending with Ligeti at the end of the 20th. The programme was made up of 25 short works, each by a different composer and arranged in broadly chronological order, resulting in a series of startling contrasts, but punctuated with equally surprising, and often very revealing, continuities.

One of the many astonishing things in Mia Hansen-Løve’s fifth film is watching Isabelle Huppert hold back tears. In one scene they smear almost involuntarily down her face, in another she transforms them into a bark of nervous laughter. Huppert plays Nathalie Chazeaux, a sixty-something Paris philosophy teacher, who paces the film with almost frantic speed while her life unravels around her.

More than just a great and serious pianist, Leif Ove Andsnes is a Mensch. His special gift in recent years has been to bring young musicians just establishing their careers together with star players like himself in beautiful and/or interesting places. I feel privileged to have heard him and his juniors in a programme of rare Sibelius melodramas in Bergen, Kurtág and Liszt in the main room of Grieg's humble home at Troldhaugen, and two shared recitals linked to the revelatory exhibition of little-known Norwegian artist Nikolai Astrup at Dulwich Picture Gallery.

All the best festivals develop organically, with a guiding hand from the best directors. When I first came to the East Neuk Festival two years ago, on its 10th anniversary, it was already a special case, thriving on the spirit of place and including an all-day Schubertiad from top international artists, many of whom were returning because they loved this special peninsula of the Fife coast so much.

After a grey start, there was a spectacular sunset around midnight on the second of my two days in Reykjavik. It's what brings one of Iceland's most brilliant younger-generation talents, pianist Víkingur Ólafsson (and yes, he's worked with Björk), back to his homeland every June. He launched Reykjavík Midsummer Music in 2012, the first full year of programming at Olafur Eliasson's ever amazing Harpa concert halls and conference centre on the harbour.

Flashback to 1981, when the Bolshoy Ballet danced Swan Lake Act Two to a tinny Melodiya recording in Istanbul's Open-Air Theatre (seats were cheap for Interrailing students). Turkey was friends with the Soviet Union then. It hadn't been in the 1950s, when Turkish pianist and citoyenne du monde İdil Biret was advised not to play a Prokofiev sonata in her motherland.

Elasticity is a surprisingly reliable test for great art. How far can you stretch, bend, or reshape a work before it loses its essence, its identity?  Hamlet, The Well-Tempered Clavier, Antigone, Pride and Prejudice can all take almost anything you can throw at them, but what about Winterreise, Schubert’s song-cycle of lost love?

In the Wigmore's Lieder prayer meetings, baritone Christian Gerhaher is the high priest. There are good reasons for this, but given that the innermost circle of Wigmore Friends pack out his concerts, you do feel that the slightest criticism might merit lynching by the ecstatic communicants. His Schubert is never less than fascinating, but 2011's Winterreise kept its distance, while last night there were more question marks hovering over a Schubertiade of mostly semi-precious stones and only the odd jewel.

Cherrypicking from 17 concerts to come up with the one by last year's Leeds International Piano Competition winner may seem a bit unfair to the French Institute's ever more ambitious annual It's All About Piano! Festival. It was hard, for instance, to miss out on the youth element, the Satie bookending the weekend's events, or for that matter the absolute star of the festival two years ago, David Kadouch, who then gave one of the best, and most intriguingly programmed, recitals I've ever heard and teamed up for a Saturday night duo recital with Adam Laloum.

It’s always heartening to see a full house for a debut recital, though when expectations run so high, the stakes for the pianist can be dangerously raised. No worries at St John’s Smith Square, though, for Seong-Jin Cho.
