"This," Lizzie Graham writes in the programme book of the current Longborough Festival, “is definitely the test of whether or not it is possible to put on a convincing Ring in a small, privately-owned country theatre.” I don’t think Lizzie or her husband, Martin, the festival’s founders and owners of the theatre, can have seriously doubted that the answer would be yes. Serious doubts seem not to be part of their entrepreneurial make-up; or if they are, they suppress them.

Britten’s coronation opera, paying homage less to our own ambiguous queen than to the private-public tapestries of Verdi’s Aida and Don Carlo, is not the rarity publicity would have you believe, at least in its homeland. English National Opera successfully rehabilitated it in the 1980s, with Sarah Walker resplendent as regent. Phyllida Lloyd’s much revived Opera North production gave Josephine Barstow the role of a lifetime, enshrined in an amazing if selective film.

In Bracken Moor Alexi Kaye Campbell inhabits similar territory to J B Priestley, whose work he admires. Like his predecessor, Campbell combines social comment with the mystical and spiritual and even chooses to set the action in pre-war Yorkshire. Orwell's The Road to Wigan Pier, published in 1937, quoted both in the dialogue and the programme, also contributes to the play's landscape.

Almost a decade on from their debut album, Tunng’s founding folktronic ethos no longer carries the shock of the new, but the sprawling and vaguely mystical collective continue to make ever more beautiful and interesting sounds. Turbines, their fifth album, is released on Full Time Hobby next Monday. To get in the mood, readers of theartsdesk can catch a world exclusive eyeful of the video for their new single “The Village”. Let us know what you think.

Sir Anthony Caro, OM, is wowing them in Venice with his masterly retrospective, but for those of us who can’t get there, there is a generous helping of his characteristic late work in his first show in Gagosian’s airy large gallery. Late Caro (he’s 89, a titan of sculpture) is a revelation in the irresistible vitality with which he imaginatively and consistently finds new things to say using one of his favourite materials: rusted mild steel.

There is a palpable communication of the artist’s own enjoyment, his intelligence and his delight

What kind of legacy will the Blair years lave on ordinary people? Some predictable answers but also some unexpected, haunting personal accounts emerge in a drama inspired by the spectacularly successful 1974 play Kennedy's Children from American actor-playwright Robert Patrick. 

The Marriage of Figaro is so much a part of Glyndebourne’s history that it’s sometimes hard to recall the details of this or that production. Michael Grandage’s current staging, though, will be easily remembered for its strong characteristics, both good and bad: for Christopher Oram’s marvellous Alhambra sets, for the brilliance and occasional vulgarity of Grandage’s direction, for its perfection of movement and timing and its almost total obliteration of the social distinctions on which the plot hinges.

They say that you’re not supposed to judge a book by its cover, but I began to grow bored with Love and Marriage about halfway through the opening credits. What seemed like endless pairs of smiling, photogenic couples swung onto the screen against a twee, brightly-coloured backdrop, and I realised I was already struggling to care.

Is the BBC taking dictation from the Gradgrindian brain of Michael Gove? According to the education secretary’s latest wacky diktat, what the nation’s children want is facts facts facts. Plus, in the teaching of history, lots of stuff about England/Britain giving Johnny Foreigner a bloody conk. So let’s give it up one more time for the Tudors, who are essentially our very own Nazis. This is less for the dodgy human rights record than their permanent status as a small-screen visitor attraction.

The pronouns have it in Alan Ayckbourn's career-defining comedy of spiralling misunderstandings, which has arrived on the West End 46 years after first hinting at the formidable talent of a dramatist who could make of many an "it" and "she" a robustly funny study in two couples in varying degrees of crisis.
