The picnic hamper’s open, the bubbly is chilled, and country house opera is starting to eat itself. When you arrive at the Wormsley Estate you enter a fantastic, baffling world. Figures in black tie stroll between topiary hedges in obedience to unstated rules, while serving staff hover a few paces behind, gliding silently in to reassert neatness and order. Children dressed in red (they’re from a local Scout group) pop up to help and guide. Then the new production of Die Zauberflöte begins and with a deft, surreal spin, the director Netia Jones bowls it all straight back at you. That’s a big part of the fun here. Jones has designed the production herself, and she clearly has quite a DVD collection.

‘All fish in flood and fowl of flight/ Be mirthful now and make melody’ writes the poet William Dunbar in the verses that Sir Charles Hubert Parry set to music as Ode on the Nativity. In David Matthews’s new Ninth Symphony, one particular fowl does exactly that. The symphony’s central movement begins on strings: an idyll of grey skies and shivering leaves. Matthews gradually introduces blocks of woodwind and brass, including a heavily stylised burst of birdsong.

Apparently it’s called ‘expectation management’. Pollux, Esa-Pekka Salonen’s new work for the Los Angeles Philharmonic Orchestra, takes its name from Greek myth. But as Salonen explains in his programme note, there’s more: lots more. It’s intended to form a diptych with a second piece called (naturally enough) Castor. It’s also part-inspired by Rilke’s Sonnets to Orpheus, and an image (Salonen compares it to Salvador Dali) of a tree growing out of an ear. And finally there’s a ‘mantra rhythm’, which Salonen heard played by a post-grunge band ‘during dinner in a restaurant in the 11th arrondissement of Paris’, which all sounds very civilised.

The opening of Mark Simpson’s new Cello Concerto is pure Hollywood. A fanfare in the low brass, an upwards rush and suddenly the screen floods with lush orchestral sound — as confident in its onward sweep as Star Wars or ‘Tara’s Theme’. Waiting, poised, in the middle of it all was the soloist Leonard Elschenbroich, for whom Simpson has said that he wanted to write a concerto that celebrated the cello’s ‘expressive and lyrical force’. He has, too. From the instant Elschenbroich entered, it felt right. The cello soared over a chiming marimba, like in Walton’s Cello Concerto. It lingered over its farewells, like in Elgar’s.

A spectre haunted the first weekend of the City of Birmingham Symphony Orchestra’s Debussy Festival: the spectre of Richard Wagner. Debussy’s relationship with Wagner began with infatuation, and ended (as so often) in open rebellion. The young decadent who declared Parsifal ‘one of the loveliest monuments of sound ever raised to the serene glory of music’ later ranted that ‘30 million Boches cannot destroy French thought’ even while, tormented by cancer, he laboured to complete three late sonatas of near-infinite subtlety and grace. But there’s always the sense, as Debussy put it as early as 1890, that ‘I don’t see what can be done beyond Tristan’.

Blue Gadoo is one of those cats whose face looks like it’s been bashed flat with a wok. He lives in New York, apparently, and his bulging eyes goggle out from Gerald Barry’s programme note for his new Organ Concerto. Check him out: the Guardian published the full note a day before the performance, which is only right because a Gerald Barry world première really ought to be national news. ‘I saw a photograph of him with a book called Sex and the Sacred in Wagner’s Tristan und Isolde,’ explains Barry. ‘By his expression I knew he was mourning the loss of atonality.’ There’s heaps more like that.

To get a flavour of Joseph Marx’s An Autumn Symphony, picture the confectionery counter in a grand Viennese café. Beneath the glass lies sweetness beyond imagining: towers of sponge cake, billows of whipped cream, and icing that shines red and orange. You wander down the display: there are Sachertortes, petits fours, candied angelica and glacé cherries. It goes on — dark chocolate glints over golden pastry and pink marzipan cushions swell beneath tangles of spun sugar. At which point you realise that what you really want is an espresso and a bread roll. And it looked like it would be such a treat, too.

Bavarian Radio Symphony Orchestra / Mariss Jansons Barbican NDR Radiophilharmonie Hannover / Andrew Manze Symphony Hall At the end of Prokofiev’s Fifth Symphony Mariss Jansons asked the Bavarian Radio Symphony Orchestra to stand up, and they refused. That’s not something that occurs in every concert; in fact, you might never see it happen. But this act of low-key mutiny is about the highest tribute an orchestra can pay to a conductor – to decline credit for the applause, handing it over in its entirety to the old maestro standing in their midst, looking shattered. A few moments later, Mitsuko Uchida presented Jansons with the Gold Medal of the Royal Philharmonic Society, but that gesture from the band was the real accolade.

‘There is something enviable about the utter lack of inhibition with which Leonard Bernstein carries on,’ wrote the critic of the Boston Globe after the US première of Bernstein’s Third Symphony, Kaddish, in February 1964 — and looking at the forces arrayed at the Barbican, he had a point. In addition to the full LSO there was the London Symphony Chorus, a narrator, a solo soprano and the Tiffin Boys’ Choir. It barely fitted on stage. And if you thought the set-up was extravagant, a glance at Bernstein’s self-written text would probably have sent you screaming from the hall. ‘Lenny’ was classical music’s original bleeding-heart superstar: the man for whom Tom Wolfe coined the phrase ‘radical chic’.

Debussy’s Prélude à l’après-midi d’un faune begins with a sigh: a long, languorous exhalation played on the lower notes of a solo flute. The flute’s usual brightness and brilliance is gone. It’s a dusky, breathy sound, made of half-shades and velvet: the musical embodiment of luxe, calme et volupté. And it’s completely impossible to imitate on a piano. Not so much because of the tone-colour — the best pianists can create wonders — but because no piano in existence can play an unbroken melody. Wind and string players, like singers, produce and control a near-continuous stream of sound. A piano, though, is essentially a box of hammers. It hits notes, and then they decay.
