Treasure our young continental European musicians in London while you can. Only last week I learned that so many of the overseas students at London's Guildhall School had stories to tell about being questioned in public (usually "are you Polish?" with the negative ramifications that implied). Certainly that was true for the Estonians, two of whom celebrated their country's 99th birthday as a republic yesterday lunchtime - the big day is on Friday; expect much more in centenary year - with assistance from their London embassy and the City Music Society.

Two young guys called Ben graced the BBC Philharmonic platform at the Bridgewater Hall – looking almost like Ant and Dec if you let your imagination wander. Ben Gernon, 27, had just been announced as the orchestra’s new Principal Guest Conductor (while predecessor John Storgårds now rejoices in the title of Chief Guest Conductor … it almost seems a bout of alternative facts is coming on), and this was his Bridgewater Hall début.

It’s just a short trip down the A1 from Edinburgh. But East Lothian – with its big skies, wide-open spaces, empty beaches and seemingly inexhaustable supply of quaint, historic villages – feels like a long, long way from the Scottish capital. Especially from the heaving, hectic Edinburgh of the August festivals season – which East Lothian’s Lammermuir Festival follows by just a couple of weeks, managing to maintain the momentum of artistic endeavour, but also providing a far more reflective, considered antidote.

Vladimir Jurowski began his latest season as Principal Conductor of the London Philharmonic with a typically bold and adventurous programme. At its core were the two Szymanowski violin concertos performed by Nicola Benedetti, and these were framed by Debussy’s Prélude à l'après-midi d'un faune and Bartók’s The Miraculous Mandarin Suite. The two concertos are stylistically distinct, the First impressionistic, the Second folk-influenced, so the pairings were apt.

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.

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.

“Bon soir, good evening! Nice to see you! To see you...” Four years after bidding an emotional farewell to the Usher Hall, the Gallic charmer is back, maybe slightly stouter, with a tinge of grey in a new beard, the great mop of curly red hair as unruly as ever. And that accent! As the anecdotes flow, stout middle-aged Edinburgers swoon as they imagine themselves drinking pastis on the Boulevard St Germain in the spring sunshine.

The earliest film collected here, 1963’s Elgar, stands up incredibly well. Some of its quirks were imposed from above: fledgling director Ken Russell was initially employed by the BBC’s Talks Department and was discouraged from using actors in his documentaries. So Elgar is packed full of reconstructions of scenes from the composer’s life, though the actors never speak and there are no close ups.

Last night’s concert at the Barbican focused on the theme of dreams and night-time, centred around the UK premiere of Dream of the Song by George Benjamin. But the one piece on the programme that did not fit with the theme stole the show. Stravinsky’s American-period masterpiece Symphony in Three Movements supplied the energy and rhythmic impetus lacking elsewhere.
