Now for something completely different. The Excursions of Mr Brouček is Leos Janáček’s least typical opera and is rarely performed. Among his tragic tales such as Jenufa and Kat’a Kabanova, the charm of The Cunning Little Vixen and the strangely heart-twisting The Makropoulos Case, the Czech composer's biting satire – in which the time-travelling anti-hero is chiefly "blotto" – faces an uphill struggle for a look-in.

"Elysian" is the best way to describe the dream gardens of Ireland's Lismore Castle in early June: lupins, alliums and peonies rampant in endless herbaceous borders, supernatural perspectives towards the main building on various levels. This year’s Blackwater Valley Opera Festival production of Gluck's Orfeo ed Euridice, not so much: easily adjustable circumstances worked too often against talented performers in the converted stables space pressed into service once a year.

The scene is Monte-Carlo, around the beginning of the last century: a carefully observed world of cloudless skies, glittering seas, high society and careless privilege shared with Death in Venice. John Cox’s staging works in cool harmony with the timeless, dangerous comedy of sexual politics devised by Mozart and da Ponte – and with the specifically English culture of country-house opera.

Wagner, in his medievalist, pan-European, 19^th century way, wanted Parsifal to be a blend of abstract and religious experience for his audiences at Bayreuth, calling it a “festival play for a stage consecration”. Questions for those performing it today include how to do justice to its philosophical baggage as well as its marvellous music, and whether to introduce new elements in the visual staging that the composer never thought of.

With a lapse of three years between Das Rheingold and Siegfried, and with only a semi-staged Walküre in between, it’s been hard to stay tuned to Amy Lane’s Ring production at Longborough.

An opera in the Hallé concert series, conducted by Sir Mark Elder, is rather like a blend of a religious observance and a masterclass in orchestral playing and singing technique.

Words and situations are one-dimensional, but the music is chameleonic, if not profound, and crafted with a master’s hand. What to do about Saint-Saëns’s Biblical hokum? In Richard Jones’s new production, the end justifies the means, with persecuted Hebrews and mocking Philistines circling two essential star turns, and Antonio Pappano’s handling of a hard-to-pace score is vivid from opening keenings to final cataclysm.

After two years of Covid-affected performances – even though there was a full season last year – Glyndebourne's annual festival is finally back in full glory. Following the big blaze of Saturday's The Wreckers, Sunday welcomed back Michael Grandage's durable production of a signature treasure, Mozart’s The Marriage of Figaro.

Interesting for the history of music, but not for music? Passing acquaintance with Ethel Smyth’s The Wreckers, a grand opera by a woman at a time (the early 1900s) when circumstances made such a thing near-impossible, had suggested so. Then along come Glyndebourne’s music director, Robin Ticciati, and a team dedicated to two years’ research in putting the full original together, including an extra half-hour of music not heard before, and it turns out to be more than that.

Thanks to the pandemic, the planned tidal surge of Fidelio productions never quite happened during Beethoven’s anniversary year of 2020. Instead, the birthday’s boy’s sole opera – beset by glitches and re-thinks ever since its creation – has rolled on intermittent waves into houses and halls around the world.
