Things you might know about Oslo: it’s expensive and the cost of a beer, wine, dinner for two – whatever your tourist yardstick – might make your hair stand on end (the cost of living is currently second only to Singapore city, according to a 2014 survey by the Economist Intelligence Unit); it’s small (population: 600,000), yet it’s also the fastest growing capital in Europe, thanks to both overseas immigration and the fact that many Norwegians are now moving to the capital; its most celebrated son is, of course, Edvard Munch.

I am currently in the middle of a project called Messiaen 2015: Between Heaven and the Clouds, a year-long series of commissions and events around the UK, exploring Messiaen’s Vingt Regards sur l‘Enfant-Jésus, curated by pianist Cordelia Williams. 

Though perhaps not quite the "long strange trip" once hymned by the Grateful Dead, Leif Ove Andsnes's Beethoven Journey has been a marathon undertaking. It has spanned four years, during which the Norwegian pianist and the Mahler Chamber Orchestra have toured the world, performing all five of Beethoven's piano concertos with Andsnes conducting from the keyboard. This week, they bring their trek to a close by performing the concertos, plus Beethoven's Choral Fantasy, at the Proms, opening on Thursday (23 July) and continuing on Friday and Sunday.

Canadian heroic tenor Jon Vickers, who died on Friday 10 July aged 88 and whose full life took him from work on a Saskatchewan farm to the great opera houses of the world, was inimitable, terrifying and titanic. Faced with the intense flavour of what follows, I can only write a sober short introduction to the magical words of our two contributors. 

The first thing that strikes you at 3am is the light, that strange disembodied glow of Norway’s midsummer midnight sun casting its rays over a landscape soaked in fantasy proportions –  sheer glacial drops of greenstone, sweet-water fjords cutting deep into the land, the forests of spruce and pine desending from steep mountainous peaks to the meadow grasses of the valley below.

Last week the 15th International Tchaikovsky Competition in Moscow was rung down with a sigh of relief for the home team, with once again a Russian pianist in possession of the gold medal, Dmitry Masleev following 2011’s Daniil Trifonov. It was all very satisfactory for President Putin as he delivered his speech at the winners’ gala, being Tchaikovsky’s 175th anniversary year, but it was not a result that many disputed. The modest Siberian, 27, is a thoughtful pianist as well as a powerful one in traditional Russian manner.

“I lately took my friend Boswell and showed him genuine civilised life in an English provincial town. I turned him loose in Lichfield, that he might see for once real civility”. In Lichfield, it’s more or less obligatory to begin with a quotation from Dr Johnson – no lover of music, although his native city does have a modest musical pedigree to set alongside its literary hall of fame.

Britten’s A Midsummer Night’s Dream opens with creepy glissandi emanating from the pit like nocturnal spirits. There is no mention in the score – this is an educated guess – for the chirrup of swifts and the hoot of wood pigeons, but this avian chorus joined the overture anyway at last week’s dress rehearsal in the open-air courtyard of Théâtre de l'Archevêché. Perhaps director Robert Carsen ordered them in as an atmospheric extra. An Aixtra, if you will.

Love Supreme, now in its third year, feels like the best of both worlds. Set in the spectacularly rolling scenery of Glynde Place, outside Lewes, it’s only a champagne cork’s flight from Glyndebourne opera house, and if you’re not camping you can share the train home with the penguin-suited picnickers. Yet the format and layout are every bit greenfield rock festival, albeit – how posh is this – with flushing toilets.

It’s a brilliantly sunny January afternoon amidst a general drama of rain at an industrial park outside Aix-en-Provence, and members of a production team are gathering for the first time in the back yard of the festival’s rehearsal studios. Some have met earlier, and three of the five singers who’ll be arriving shortly know each other thanks to the connections already made through the European Network of Opera Academies.
