Richard Wagner has probably only himself to blame if his operas have become a laboratory for the testing-to-destruction of the intellectual preoccupations of that Opera Führer of our time, the stage director. Wagner it was, after all, who transferred the mythic concept of concealed meaning to the opera house: Wagner who recreated legend as psycho-social allegory, and made musical narrative the handmaiden of philosophy and political ideology.

In 1981, when I last came to Bayreuth, the festival still seemed to be a battleground between the German Left and Right, between the blame faction and the guilt faction, between the commie East and the fat-cat West. Plus ça change. Without quite openly taking sides, Sebastian Baumgarten’s new staging of Tannhäuser rings some cracked old political bells while, apparently with Bayreuth’s connivance, candidly parodying most of the thinking that underpins this admittedly somewhat raw, yet for Wagner absolutely crucial early work.

Longborough has its Mozart (this season a not wildly exciting Così fan tutte), and it has its Verdi (this year Falstaff). But its real heart is in Wagner, and in particular The Ring, now – in its third year – up to Siegfried. Wagnerites infest the car parks and the picnic lawns. The man who borrowed our corkscrew at supper time had seen six operas in one week at Bayreuth, and on his one night off had gone to Munich to see Rienzi, the longest Wagner night of the lot. Longborough is decidedly his kind of place.

The Hallé Orchestra, enlarged for the occasion with harps, anvils, horns and such, was in its place on the platform. Sir Mark Elder made his entrance like a surgeon about to embark on a complex and energy-draining heart bypass operation. And the lights went out. On purpose. A spotlight picked up a man in a white shirt with long hair mounting the platform and making his way to a small table, chair and reading lamp mid-stage. It was Richard Wagner – in the form of actor Roger Allam. Pure melodrama.

After years of planning, Opera North's Ring cycle gets under way. The orchestra pit at the Leeds Grand Theatre is too small for Wagner's oversized orchestra. So this is a concert staging, to be repeated in the coming months at The Sage Gateshead, Birmingham's Symphony Hall and The Lowry in Salford. It's really a blessing, meaning that production staff don't have to grapple with Wagner's extravagant stage demands in order to make the impossible appear tangible. What Opera North have done is engage lighting designer Peter Mumford to create a concert staging.

What next - Boulez and Daniel Barenboim in Tchaikovsky and Rachmaninov? The two numbered Liszt concertos are probably as far as they're going to go in lacier romantic repertoire, and last night it didn't feel far enough to justify the predictable standing ovation.

Travelling by Eurostar, or plane, to the continent and buying a ticket, all for less than the cost of a Covent Garden stalls seat, might entice if you wanted to see a certain opera, singer or conductor. But to go so far for the look of a staging? Well, the Catalan company La Fura dels Baus’s phantasmagorical ENO production of Ligeti's Le grand macabre has left some of us hungry for more, which so far means going abroad to find it. Ultimately their latest Wagner doesn't always rise to the expected visionary heights, but it does boast world-class music-making and, wonder of wonders, real interaction between the singers on a human scale.

More phantasmagorically beautiful than it ever had any right to be given its subject, Francis Ford Coppola’s Apocalypse Now begins as a nightmare, or a delirium, with thup-thup-thupping helicopters ghosting in and out of the frame in front of the jungle and wisps of yellow smoke rising in the foreground. Cymbals, noodling guitar and a tambourine played by The Doors on the track preface the voice of Jim Morrison, who exhaustedly croons the opening lines of “The End”. An unseen napalm strike suddenly engulfs the palm trees.

Paul Taylor's Roses is called Roses because, well, because it is. There are no roses here, no flowery sentiment, no overwrought angst and emotion. This, one of Taylor’s most beautifully serene works, is the smell of roses on a still May evening: fleeting, evanescent and heart-breakingly beautiful. It is also some of the most magisterial - and startlingly original - choreography, even a quarter of a century after it was first made.

Be different - take a festival break in Europe instead of the UK, and catch a different landscape. While artists in both new music and classical are constantly circling the world in search of more picturesque settings, you can find your alternative Glasto in Denmark or Belgium, or you can find favourite chamber musicians in Austria rather than London. theartsdesk brings you listings of this year's major European festivals: rock in Sonar, Sziget and Stradbally, opera in Bayreuth, Verona and Salzburg, dance in Vienna, Epidauros and Spoleto, visual arts in Istanbul, Zurich and Avignon. This is the indispensable clickable guide to a cultured break in Europe.
