Silence. Near-darkness. Oozy weeds of orchestral strings twist in the mind of Edward Fairfax Vere (John Mark Ainsley), remembering the tragic events of 1797 when he was Captain of the HMS Indomitable. From that awe-inspiring start through to one of the most upsetting of onstage murders, perhaps the greatest parade of major and minor chords in all opera and beyond to some kind of redemption, Michael Grandage's Glyndebourne production - his first in the operatic sphere - of Britten's grandest opera moves with a simplicity and grace which fit this tight little craft of an opera house very well indeed. It's the singing and the orchestra in perfect balance which packs the punches, rather than any one idea in the staging, but that's not necessarily any defect.

For many of us, this was bound to be an emotional evening. Noëlle Mann, doyenne of all things Prokofievian on the editorial, archival, teaching and performing fronts, died peacefully at home last Friday, and it was to her that Vladimir Jurowski dedicated a typically bold programme of Prokofiev's late epic for cello and orchestra, the Symphony-Concerto, and a big but rather less focused symphony by his closest composer-friend Nikolay Myaskovsky. Perhaps it's presumptuous to speak for the departed; but I could hear Noëlle responding vitally to her master's voice, applauding Jurowski for championing the lesser-known figure but sternly proclaiming the verdict shared by most of us: that while Prokofiev was touched by the divine spirit, poor, diligent Myaskovsky clearly wasn't.

This is the fifth time on theartsdesk that a review has been headed as above - so you must be thinking it had better be justified or bribery will be suspected. But it's not just the phosphorescent fascination that flickers around the charismatic young LPO principal conductor Vladimir Jurowski that draws the crowds, it is his inquiring programming. Last night it was another of those games that one couldn’t resist, if a game, in the end, of two halves.

Whoever said it was better to journey than to arrive might have been thinking of Sibelius. The arrivals can be pretty spectacular – as here in Osmo Vänskä's tremendous account of the Second Symphony – but the getting there – or not – is what this music is all about. When Vänskä conducts Sibelius he doesn’t just traverse the musical landscape, he inhabits it, breathing it in, feeling its pull, overawed at the threshold of where sound becomes silence and vice versa. He is Sibelius’ eternal Wanderer. Barenboim may have stolen the column inches this week but Vänskä has stolen hearts and minds. Whether or not you have ever experienced his Sibelius – get thee to the two remaining concerts.

As was hoped, Osmo Vänskä, the livewire music director of the Minnesota Orchestra, showed us exactly why he's the greatest living Sibelian last night in the first concert of the London Philharmonic's Sibelius cycle. Ducking and diving, crouching and corralling, Vänskä worked the podium like some mad ant, scurrying now over to the violas, gesturing now manically to the horns, his hands rattling fiercely like a jilted Old Testament prophet, sculpting, harrying and rousing the orchestra to peaks and troughs of ecstasy and despair.

Laid-back Tenerife and Gran Canaria won't know what's hit them when the London Philharmonic Orchestra and its principal conductor Vladimir Jurowski land next week. The islands can expect to be sense-bombed by the jungly exuberance of Szymanowski and devastated by the scorched-earth tactics of Shostakovich at his most extreme. Even Londoners used to the highly sophisticated assaults of the city's most challenging orchestral partnership, and faced with the same programme last night, may have been taken aback by the keenly directed electricity of the occasion.
