Glyndebourne nature, it seems, runs along as smoothly as the much discussed new wind turbine on the hill. Within the theatre, though, all is flux: director Melly Still and Vladimir Jurowski, conducting an incandescent London Philharmonic Orchestra, show just how flexible it's possible to be with the viciousness and the vivacity in Janáček's kaleidoscope of birth, copulation, death and a redemption of sorts in celebration of the natural order.

When telling a complex musical story, handle with care. Interpreters need have no fear of composers who find selective, tone-friendly angles in their literary sources, like Janáček with Gogol’s Taras Bulba in last night’s searing finale, or Zemlinsky with Andersen’s The Little Mermaid, the saturated climax of the previous evening. But what about Dvořák in oddball, potentially enriching mode, setting every jot and tittle of a folk ballad without actually using words or voices?

Katie Mitchell’s production of what many regard as Janáček’s greatest opera began life 10 years ago on the stage of Cardiff’s New Theatre; and there are times in this revival when you feel its director Robin Tebbutt’s yearning to be back in that constricted environment, so much better suited to the stifling world which destroys the work’s repressed, self-loathing heroine.

It was partly as penance for having missed the previous evening's Czech festival that I arena-prommed for last night's Moravian finale, to be happily strafed by the nine extra trumpets of Janáček's Sinfonietta.

Here we are again. Marvel as you enter at the aptly gaudy lighting of Albert's colosseum, but know that unless your place is with the Prommers towards the front of the arena, the musicians will often sound as if they're in another galaxy - maybe one hinted at in the George Herbert words, if hardly the Judith Weir music, of the opening BBC commission, Stars, Night, Music and Light. Though spattered with Messiaenic orchestral paint - not to mention the obbligato sniffalong from my annoying neighbour - it felt like a very tame, rather olde-British gambit.

Robin the boy wonder, as he was somewhat patronisingly dubbed during his prodigious rise to conducting stardom, will make a bracing Batman for Glyndebourne Festival Opera when he takes over from current music director Vladimir Jurowski in January 2014.

Janáček’s stark Prelude is a stunner: there’s no conventional beginning, no conventional thematic development; it simply starts, as if a light switch has been flicked on, and the baleful opening theme is distorted, repeated, squeezed until it leads into an extraordinary stretch of solo violin writing. Based on Dostoevsky’s novel,  Janáček’s final opera isn’t a faithful adaptation – it’s a selection of loosely linked scenes spread over three concise acts.

A glance at the programme hinted at the identity of the orchestra: you don’t perform Prokofiev’s Scythian Suite and Janáček’s Sinfonietta in the same evening unless you’ve industrial quantities of brass and percussion to spare. This was riveting, transcendent stuff, and the most uplifting evening I’ve spent in a concert hall for years. Plus, the echoing barn of Leeds Town Hall is the ideal size for a 170-piece orchestra, a perfect place to experience Janáček’s hocketing brass fanfares. This was the closing concert of the NYO’s winter tour, and an incredible achievement for an orchestra that only assembled two weeks ago.

In the last year of his life he was, as a colleague noted when we learned of Charles Mackerras’s death, the wise old gamekeeper in the spring forest of Janáček's Cunning Little Vixen. No wonder Mackerras, we were told last night by his conductor nephew Alexander Briger, wanted that most ecstatic celebration of the natural order for his memorial, just as Janáček had had it played at his funeral. Was it trivialised by an encore number from Mackerras’s deliciously arranged Sullivan potpourri-ballet, Pineapple Poll? Not a jot, mate.

This month’s releases include two contrasted crossover discs, one in tribute to Armenian Orthodox church music, the other by, er, Phil Collins-era Genesis. There’s an Elgar oratorio, and a disc of choral music inspired by the untimely death of a young royal. Orchestral fireworks can be found in a recording of a well-known British work and there’s some approachable Modernism from a modern Polish master. There’s a thrilling compilation of viola concertos, and a classic recent set of Rachmaninov piano concertos reappears at a lower price. Gershwin turns up on an interesting French disc of 1920s music for piano and orchestra, and a work more often heard in a gaudy orchestral transcription is given an excellent solo piano reading by a young Welsh pianist. There’s an effervescent box of Baroque keyboard music played on piano, and a classic set of Shostakovich from the Brezhnev years reappears after a long absence. Chamber fans should check out Gidon Kremer’s latest release, and those unhappy in love should avoid revelatory readings of two of the best string quartets ever written.
