Buxton International Festival’s opera scene is clearly back on track for 2022, and its most substantial production a taut and tension-filled presentation of Rossini’s La Donna del Lago.

Irish soprano Jennifer Davis, a stunning Elsa in this Royal Opera season's revival of Wagner’s Lohengrin, was the lure to sit through Jan Philipp Gloger's Mozart Così again (the title, by the way – "All Women Do It" – belies the complexity applied to a schematic plot). As it turned out, the mixed-up couples were all love’s young dream, which made it all the more of a shame that this production remains determined to squash their hopes and even their new matches.

Manchester Collective were back on home ground last night in the tour of a programme featuring the first performances of a new song cycle by Edmund Finnis, Out of the Dawn’s Mind. Soprano soloist was the amazing Ruby Hughes.

It was home ground for her, too, in a sense: as a former student at Chetham’s School of Music she’s an old friend of the Collective’s leader and artistic director, Rakhi Singh.

There probably isn’t a more able translator of vintage drama than Martin Crimp, the playwright whose 2004 version of Pierre Marivaux’s 1724 play about deceit, greed and sexual politics has been revived at the enterprising Orange Tree. The finale has been slightly tweaked now, which helps repurpose the play as a work with today’s interest in gender fluidity in its sights.

Handel’s operas have long posed, and still pose, severe problems for the modern theatre, and especially the modern director – all those endless streams of wonderful but emotionally more or less generalised arias hitched to interchangeable characters in fabricated love stories about crusaders or Roman emperors or oriental potentates.

"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.

You know great singing when you hear it. In Handel, for me, that was when Lucy Crowe took over a Göttingen gala back in 2013; in Mozart, most recently, it came from Emily D’Angelo making her Royal Opera debut in La clemenza di Tito. Last night, in an opera of genius from first note to last, both shone, but neither eclipsed other performances or took the spotlight from the ravishingly beautiful playing of Harry Bicket’s English Concert.

Bent Sørensen has christened his new harpsichord concerto Sei Anime: “six souls”. The six concise movements, written for Mahan Esfahani and a chamber-sized orchestra, are modelled, apparently, on the dance movements of a Bach keyboard suite. But as Sørensen explained from the stage – standing next to Esfahani’s gleaming black harpsichord – two further anecdotes explain the name. It’s borrowed from a range of French womenswear, seen in a Copenhagen shop: the audience laughed.

JS Bach’s Passions as music theatre? Well, why not? Whatever the aura of untouchability around these works, they were always conceived as part of a bigger picture: a communal sacred ritual in which the divide between performer and audience wasn’t so much blurred as nonexistent.
