Like Proust's In Search of Lost Time, Abel Gance's Napoléon is the monument of a genius badly in need of self-editing. In both instances, everything testifies to the singular vision of the artist - in Gance's case, his innovations in the field of film technology, from hand-held-camera mayhem to three-screen novelty in the final sequence which ends up in tricolour (earlier, tints and tones in greens, purples and reds, inter alia, articulate the underlying moods of certain scenes).

What's a world-renowned mezzo-soprano in her middle years to do? Slimline of voice, tall and handsome in person with piercing and slightly intimidating blue eyes, Stockholm-born Anne Sofie von Otter isn't likely to sing what is known in the operatic world as "all those old bag parts", though she's a good enough actress to have carried off a few.

It felt oddly disrespectful showing up in time for Schumann's wake on the fifteenth and final day of this year's Oxford Lieder Festival. Having started with the early piano music and many of the chamber works before moving on to Schumann's annus mirabilis of song, 1840, with frequent leaps backwards to influences and forwards to the influenced, pianist Sholto Kynoch’s labour of love reached the troubled final years dogged by whatever that insanity for which Schumann was institutionalised might have been – bipolarity, syphilis, poisoning for the mercury used in its treatment.

Josquin: Masses The Tallis Scholars/Peter Philips (Gimmell)

Populist playwright Peter Shaffer, who died in June, gets a rapid honour from this flagship venue, which – aptly enough – is putting on his most popular play. So popular in fact that it has already sold out and is therefore critic-proof. Directed by one of our best youngish directors, Michael Longhurst, and with live music by the Southbank Sinfonia, this spectacular show is certainly a hugely entertaining evening.

It's harder for young professional musicians to be judged in standard repertoire – the very greatest music, in short – than to make their mark tackling the unknown in a wacky venue. High levels of energy and technical skill married to interpretations with something to say are what it takes, and what we got from the London Firebird Orchestra last night.

His transformational Brahms series with the Scottish Chamber Orchestra may have been truncated by slipped disc troubles - he was much missed at Glyndebourne too - but Robin Ticciati is back with renewed energy and purpose. To judge from the brilliant but focused party they seemed to be having with Mozart's "Jupiter" Symphony last night, the players are as overjoyed as he is.

We’re in Gdańsk for the launch of the I, Culture Orchestra (sounds like an Apple product, someone points out). The new outfit has Sir Neville Marriner as guest conductor, at 87, still on sparkling form. The orchestra has brought together young musicians from across Eastern Europe “to encourage better cultural understanding” between Poland, Belarus, Ukraine, Moldova, Georgia, Armenia and Azerbaijan.

Pace-perfect musical articulation and meaningful surprises in the direction: both were to be expected after the conductor-generated sludge and the production overkill of the new Royal Opera Così fan tutte. Mark Wigglesworth has form in Mozart at ENO, with the best of Cosìs way back and a bewitching revival of The Magic Flute this year. Last night he and the ENO Orchestra put no foot wrong. Richard Jones, his dream first-time collaborator, offered the expected twists and symmetries though perhaps not all the connections in between.

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.
