Natural disaster, in the shape of a metaphorical sea-monster ravaging classical Crete, might make a director's imagination work overtime on Mozart's first, jagged masterpiece. Alas, only unnatural disasters have been inflicted upon us in productions at Glyndebourne, ENO and the Royal Opera, with singers going some way to make amends. Now, at last, the green and pleasant valley of the Wormsley Estate has given birth to a clear and sober staging by Tim Albery that gives both the human beauties and the inhuman surrounding phenomena of the score their due.

Mozart operas on period instruments – it’s hardly a new idea, but it’s still the exception rather than the rule. The 18th–century sound has a lot to offer in Don Giovanni, as Ian Page and his Classical Opera Company demonstrated this evening. Clear string tone and vibrant woodwind colours were the order of the day. There was plenty of drama too, with Page expertly pacing the narrative and drawing an impressive and often robust tone from his modest forces. He also assembled a fine cast, no superstars here but rather a well-balanced and well-integrated ensemble.

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.

Mozart: Serenade in B flat major, 'Gran Partita', Royal Academy of Music Soloists Ensemble/Trevor Pinnock (Linn)

Sunlit golden mean or slightly hazy middle-of-the-road? Conductor-director Iván Fischer's fully costumed and imagined concert of The Magic Flute - or perhaps it would better have been titled Die ZauberFlute given its intelligent mix of sung German and English dialogue taken by six excellent young British-based actors - was always going to be hard pressed to match the recent, hyper-communicative English National Opera/Complicite revival.

Unquestionably one of the greats as a performer, Danish-Israeli violinist and conductor Nikolaj Znaider divides opinion over his forthright views in interview: either honourable and refreshingly candid, or troublingly indiscreet. After an hour and a half with him between the two finals of the Carl Nielsen International Violin Competition in Odense, I plump fervently for the former.

Bach: The French Suites Peter Hill (piano) (Delphian)

Francis Chagrin: Symphonies 1 and 2 BBC Symphony Orchestra/Martyn Brabbins (Naxos)

From the more or less inconsequential wit and bravura of The Barber of Seville to the profound comic psychology, social nuances and unparalleled musical genius of The Marriage of Figaro, and from the silly antics of Sam Brown’s Rossini to the style and brilliant stage management of Tobias Richter’s Mozart, is a good lesson in music theatrical history played backwards.

“We are at a time of present crisis.” When Sarastro addressed his boardroom of business-suited acolytes last night, there can’t have been many in the Coliseum whose thoughts didn’t turn to English National Opera. Even by the standards of a company that has spent most of its history fighting for survival, 2015 was a year of unprecedented difficulty. Whether crisis becomes catastrophe remains to be seen, but there couldn’t be a more emphatic portent of success, a better-timed metaphor, than this Magic Flute.
