It should have been a complete disaster. Not announcing your festival’s programme until barely a week before it started ought to have guaranteed that nobody knew about it – no press, no audiences, other plans made, other things booked.

But still they came. It’s testament to the Cottier Chamber Project’s now firmly established place in Scotland’s summer musical life – this is its sixth year – that even keeping audiences in the dark as to what was planned didn’t deter them.

“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.

London has been missing out on Boris Giltburg for too long. He's been playing Shostakovich concertos back to back with Petrenko in Liverpool, and the big Rachmaninov works up in Scotland (see theartsdesk's review today of the latest Royal Scottish National Orchestra programme).

In 2007 Maxim Vengerov had to withdraw completely from violin playing, and stayed away for four years. He had suffered the after effects of a weight-lifting injury to his shoulder, and needed surgery. But he also described at the time that he felt he needed to re-learn the instrument. If people – like the writer of last night's programme introduction – now refer casually to his “effortless virtuosity”, it is clearly something which has been acquired with an intense effort and sense of purpose. 

Renée Fleming recently announced her imminent retirement from the opera stage. But she has no plans to stop performing, and will instead devote her time to recitals and concerts. Yesterday’s excellent performance with the BBC Symphony Orchestra bodes well for her new career focus. And she’s not one to rest on her laurels, here giving UK premieres of two new works written for her voice, ever the adventurous artist, always playing to her strengths.

It was a simple yet beautifully elegant way for the Scottish Chamber Orchestra to kick off its 2016 chamber concerts: a recital for flute, viola and harp, with Debussy’s beguiling Sonata as the centrepiece, and other contrasting music for the same trio orbiting around it.

If the London Symphony Orchestra sounded simply magnificent in this programme of 20^th century French music, it was their restraint that caught the ear rather than the demonstration of an orchestral engine at full throttle for which they are justly renowned. Tonal refinement and fastidious attention to detail were the key signatures of the evening, as they had been for Debussy's Pelléas et Melisande at the weekend.

Ask opera-lovers to name their favourite one-acter and chances are the choice will be L’enfant et les sortilèges. Colette’s typically off-kilter fable of a destructive kid confronted with the objects and animals he’s damaged is set by Maurice Ravel to music of a depth which must have taken even that unshockable author by surprise. Ravel’s earlier L’heure espagnole, on the other hand, is much less likely to be top of the list.
