On an Edinburgh afternoon of torrential rain close to the winter solstice, what ecstasy to be transported to an ancient Greek midsummer day, a Claude landscape with shepherds calling across the hills, painted in the most translucent colours by Richard Strauss in his late mastery. All it needs are world-class voices and an orchestra that glows; it got both in Scottish Opera’s concert staging.  

“But that’s what they’re paying for!” replied my son as we, a little shellshocked by the previous three hours, skirted Trafalgar Square on the way home. I had reservations about some key components of the alchemy that produces great theatre, but none about the spectacle, even more impressive (as we subsequently agreed) than the big Cirque du Soleil extravaganzas that cost a helluva lot more for a seat in Vegas.

Mami Wata is the female West African water god still worshipped in Iyi, a fragile, matriarchal village redoubt against modernity. Writer-director C.J. “Fiery” Obasi’s third film makes Iyi a battleground for African identity, in a glistening black-and-white fable played out to the sea’s constant, low crash and wash.

To coincide with the National Library of Scotland’s first bi-lingual exhibition Sguel/Story, an exhibition in English and Scottish Gaelic which celebrates stories and storytelling, the library presented a performance of newly reinterpreted Gaelic ballads with string quartet arrangements from composer Ned Bigham.

It was more than a decade ago when I first saw Rachel Sermanni in concert, in the upstairs room at The Old Queen’s Head in Islington, London, for a Nest Collective night. She had yet to release her debut, 2012’s Under Mountains, but was already making an impact as a stage performer.

Let’s set aside, to begin with, the question of the concept, other than to praise it as consistent. Most vital about this brave new Rheingold is the vindication of director Barrie Kosky’s claim that “what makes a Ring production interesting is the detailed work within the scenes between the characters”. With a conductor as intent on clarity and meaning as Antonio Pappano, and a true ensemble of performers willing to go along with him and Kosky, the battle is three-quarters won.

Humans are unsettled by incomplete data, unanswered questions. Show us dots on paper, and we’ll join them to make a picture. Show us objects in the night sky, and we create worlds.

All that glitters, titular treasure included, is dangerous childsplay in Richard Jones’s third UK staging of what Wagner called the “preliminary evening” to the three main operas of The Ring of the Nibelung. It’s nothing like the previous two, for the Royal and Scottish Operas, in some ways disconcertingly minimal and occasionally ugly to look at. Yet everything adds up and unlike the cast for his Valkyrie, this team has the perfect mix of vocal and acting gold.

At a time when every other theatre is offering an alternative Christmas show, what to make of the Royal Opera House’s first collaboration with Lost Dog, aka director-choreographer Ben Duke, who has come up with the most un-merry topic imaginable? Meet Medea, the vengeful sorceress of Greek myth, who butchered her brother, nobbled her ex’s new bride and murdered her own children. The Wind in the Willows this is not.
