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.

It was a massive but never overbearing three-parter, a three-and-a-half hour celebration, a mini-festival of youth and experience. Wouldn’t we all want to mark a major birthday in the company of friends of all ages?

Not many people write conspicuously brilliant tweets, but Elizabeth Watts is someone who does. Working on the most demanding aria on her stunning new CD of operatic numbers and cantatas by the lesser-known of the two Scarlattis, father Alessandro rather than son Domenico, she tweeted: “Good news – I can sing 88 notes without a breath. Bad news – Scarlatti wrote 89.”

“People think when a person becomes old, he has to become serene,” declared that great pianist Claudio Arrau in his mid-seventies. “That’s absurd. The expressive intensity is, I feel, much stronger, much more concentrated in my playing than years ago.” You could argue the same for Stephen Kovacevich at his 75^th birthday concert, though in the case of Schubert’s final, B flat Piano Sonata, was it entirely intensity that had him racing through a work that, back in 1982, he took about 10 minutes longer over, albeit with repeats?

“Whatever happened to Stephen Bishop?” is not a question likely to be asked by followers of legendary pianism. Born in San Pedro, Los Angeles on 17 October 1940, the young talent took his stepfather’s name as his career was launched at the age of 11. Later he honoured his own father’s Croatian "Kovacevich", by appending it to the “Bishop”. Now it’s plain Kovacevich carved in the pantheon of similar yet unique sensibilities like those of Arrau, Pollini, Richter and Zimerman, alongside masterly exponents of mostly different repertoire like Martha Argerich.

This Barbican concert began with a Mendelssohn overture and ended with a Haydn symphony. But on stage were the BBC Symphony Orchestra and Ilan Volkov. What did you expect in between, a Mozart piano concerto? Not likely. Instead they gave the first performance of No.48 (night studio) by Richard Ayres. English-born but resident in the Netherlands and working mostly on the Continent, Ayres has impeccable post-Minimalist credentials (studies with Louis Andriessen and Morton Feldman) which do no more than hint at how his music behaves – like a kid in a well-stocked acoustic sweet-shop.
