Is there something about the start of a new cultural season, or indeed the Proms, that make classical music’s conductors rush to jump ship? Consider this. Last Friday, two days before his pair of Prom concerts with his American outfit, the Cleveland Orchestra, Franz Welser-Möst, so diffident on the outside, resigned from his important European post as the Vienna State Opera’s music director with immediate effect. Irreconcilable artistic differences were cited. 

Peter Sellars’ work used to be about making a statement. He would dislocate texts from contexts, subvert musical suggestion and ignore written statement for the sheer joy of the artistic friction it would generate. The beauty of his St Matthew Passion staging however, first seen in 2010, is that it does nothing of the sort.

After Monday’s Respighi extravaganza at the Proms, it was back on the rainbow express for more wonders of orchestral colour last night. In the young Stravinsky’s large-scale signing-in and poor depressed old Rachmaninov’s signing-off, you could trust Sir Simon Rattle’s Berlin army of generals to turn in any amount of subtle colours.

Conductor Marin Alsop was welcomed like Britannia herself at last night’s concert, an astute partnership of John Adams’ vivacious hybridism and Gustav Mahler’s colourful patchwork quilt of a symphony.

After the enervating excesses of Salome and Elektra at the weekend, the abundance of notes at the Proms continued in a piano recital and an orchestral showstopper, but this time with built-in air conditioning. After all, both 22-year-old Benjamin Grosvenor and septuagenarian Charles Dutoit are absolutely in control of the colours they make, very occasionally too much so. But it was a rainbow-hued day inside the Cadogan and Royal Albert Halls, culminating in a spectacular and perhaps unrepeatable Respighi triple bill of Roman impressions.

How much familial dysfunction and lust - whether for sexual gratification or revenge - can one take in a single weekend? Salome and Elektra back-to back may on paper seem like a feast of divine decadence but no sooner had one become accustomed to the sickly sweet air of the former when the putrefaction of the latter (I always think that Strauss’ orchestra is in the final stages of decay with Elektra) filled one’s nostrils - and ears.

So here’s where I join the ranks of Old Opera Bores by declaring this Salome, Nina Stemme, the best I’ve seen since Hildegard Behrens in 1978, and this Salome as in Richard Strauss’s Wilde opera from Donald Runnicles and his Deutsche Oper Berlin ensemble categorically the most near-perfect. It’s also the first time I’ve had a group of very loud, rude people behind me shouting “sit down” when I stood at the end (and John the Baptist’s God knows I don’t do that often).

About 10 minutes into the Brahms Third Symphony I wanted to check a name in the Budapest Festival Orchestra’s programme. I dared to turn a page. Bad idea. Such preternatural stillness had settled over the sold-out Royal Albert Hall that the gesture could probably have been spotted from the balcony. A motionless, virtually breathless audience is a rarity even at the Proms, where quality of listening is venerated; still, to hold around 6000 people quite so rapt with attention is an extraordinary skill in orchestra and conductor.

The first of this year's two Proms by the Budapest Festival Orchestra had looked like a rather strange confection, on paper at least. With eleven scheduled contributions, and only two of them destined to make it into double figures, its timings had even given it a passing resemblance to a short but eventful cricket innings (there were also three unprogrammed extra items, but more of those later). 

Even as orchestras began to sound more and more alike, there was the Czech Philharmonic. And many of its notable characteristics remain to this day: a modest, homespun quality, warm and engaging and full of bright-eyed distinction in the woodwinds.
