To catch the searing desolation of a lover scorned, you need to be the complete artist, with temperament and technique in perfect equilibrium. Mezzo Christine Rice has taken us from Berlioz's Marguerite and Mozart's Donna Elvira at English National Opera via Birtwistle's Ariadne to Haydn's, and - most taxing of all - the end of an affair by telephone in Poulenc's La Voix Humaine.

Colin Matthews’s arrangements for orchestra of the 24 Debussy Préludes (originally commissioned by the Hallé) have been widely admired. The BBC Philharmonic’s concert, conducted by Nicholas Collon, at the Bridgewater Hall on Friday night began with three of Ravel’s five piano Miroirs, two of them orchestrated by Matthews (one a world premiere) and one by the late Steven Stucky.

What's not to like, or love, would have to be the sensible response to both the opening programme of Kings Place's year-long Cello Unwrapped festival at Kings Place and its life-enhancing execution.

The cello is so deeply engrained in my fingers, my imagination, it’s part of my being – my life would feel amputated without it. You fall in love with the instrument, the music, and then you embark on the life-long task of trying to get closer to that beguiling musical ideal. That’s the drug, the contract you sign with the devil. Every day I think how lucky I am that I can dive into a score and work at it physically.

August 1914, September 2001, all of 2016: these are the dates Hungary's late, great writer Péter Esterházy served up for the non-linear narrative of his friend Péter Eötvös's Halleluja - Oratorium Balbulum. Its Hungarian premiere in one of the world's best concert halls, part of the astounding Müpa complex on the Danube in Budapest, was bound to challenge Prime Minister Viktor Orbán's anti-immigrant policy with the libretto's talk of borders and fences, and fear of the other.

Has any living pianist had a richer or more charmed life than Idil Biret? As a child prodigy she studied in Paris with Nadia Boulanger and Alfred Cortot, and both there and in Germany with Wilhelm Kempff. At the age of four she was reproducing Bach Preludes and Fugues on the family piano in Ankara simply from hearing them on the radio. When she was seven the Turkish Parliament passed "Idil's Law", enabling not her but also other gifted children to study abroad.

Gone, it seems, is the era of epic three-part Proms. Sunday afternoon's programme, partly billed as a children's hour, might have pleased pianist and pundit Stephen Hough, whose recent broadsheet plea for shorter concerts somewhat overdid the need (lunchtime events already cater to concertgoers in a hurry very well, and the Proms has its late-nighters too). But it left many of us wanting more, not just of Ravel in the second half but also of the distinctive Simón Bolívar earthiness, which was given free rein only in one spirited encore.

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.

It’s impossible to get the measure of the Cheltenham Music Festival in just one day. Lasting more than a fortnight, this is the festival that made the running in postwar British music: that helped put Malcolm Arnold and Robert Simpson on the map and defined a genre - the “Cheltenham Symphony”. Times change and financial pressures increase, but under the artistic directorship of Meurig Bowen, Cheltenham is still a powerful (if undervalued) force in contemporary classical music. Of the 120-odd composers in the 2016 Festival, at least one third are alive.

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.
