The new Glyndebourne production of Rossini's Il turco in Italia has a truly winning smile on its face and a spring and a dance in its musical step. It is brimful of fun and good ideas, conveying the sense that a lot of joy has been had in its making. As one cast member tweeted during rehearsals a couple of weeks ago: "I have not stopped laughing and living my best life all day."

The Southbank Centre automatically stuck the trusty “Bohemian Rhapsodies” headline on this London Philharmonic Orchestra concert of Czech music streamed from the still-deserted Royal Festival Hall. Given Janáček’s presence on the bill, they should have made that “Moravian” as well. I know – get a life.

The LPO, and its soon-to-depart chief conductor Vladimir Jurowski, began its 2020 Vision season back in February. It set out to mix and match the music of three centuries and show how it echoes in contemporary works. Well, little of that turned out quite as planned: this final concert at the Royal Festival Hall was meant to premiere Sir James MacMillan’s new Christmas Oratorio, now scheduled for the Concertgebouw in Amsterdam on 16 January. That outsourced event feels like a saddening symbol of Britain’s interlinked catastrophes this year. 

Colette’s sharply fantastical libretto for Ravel’s second one-act opera imagines wrongs exercised upon objects and animals by a naughty child revisited by the victims upon the perpetrator.

There was a rainbow over the Royal Festival Hall as I crossed one of the Hungerford foot bridges for the first time in six months. The lights and noises inside did not betray the augury. Was it the sheer hallucinatory pleasure of being within the auditorium with a handful of other spectators watching and hearing a full orchestra after what felt like a lifetime?

The absence of live concerts is not just affecting the "in the flesh" audiences, but also having a knock-on effect for the Radio 3 audience, used to hearing a live or as-live concert every night of the week. The BBC have instead gone to the archive of recentish concerts to keep the In Concert strand alive, and last week’s schedule (20-24 April) presented an array of appetising concerts showing the best kind of enterprising programming.

Three works two centuries apart, two of them rarities, with 100/200 years between each: that's no guarantee for programming success, and no way to fill a hall (though the London Philharmonic Orchestra admin deserves a good medal for the intricacy of its “2020 Vision” series planning, linked to the Beethoven anniversary and explained by Gavin Dixon in his review of Vladimir Jurowski’s launch concert earlier this month).

It’s Beethoven with everything for 2020, the composer’s 250th anniversary year. But the London Philharmonic has devised an interesting approach for their Beethoven-themed programming. “2020 Vision” is a series of concerts which couple a work by Beethoven, or occasionally one of his contemporaries, with a piece written 100 years later and another written 200 years later.

Of Wagner's four Ring operas, Siegfried poses the biggest casting problem. Most heroic tenors with the lungs to last the evening are not going to be ideal incarnations of the stroppy adolescent who learns and fights his way through an often nightmarish fairy-tale landscape. Torsten Kerl, not an agile mover to say the least, certainly wasn't.

For better or worse, because of Visconti’s classic film the Adagietto of Mahler’s Fifth Symphony now inevitably means Venice in its gloomiest moods. So there turned out to be a grim timeliness in a performance on an evening that coincided with the most devastating “acqua alta” to flood the city in half a century. Yet, in keeping with everything he does with the London Philharmonia Orchestra, Vladimir Jurowski’s reading at the Royal Festival Hall made us think afresh about an iconic work and dispel its more hackneyed, reach-me-down associations.
