Weird, quirky Hollywood Werner can obscure the fierce visionary who warred with Kinski in the jungle. This is even true of many of his own features since moving to LA which, like his peer Wenders, usually pale next to his reverent, supernal documentaries. Thomas von Steinaecker’s conventional doc emphasises his latter-day, parodic cult stardom but, thanks to Herzog’s enthusiastic engagement, still gets valuably close to his heart.

Those were happy days back in 2014 when, justifiably flushed with the success of the Royal Opera’s Tristan und Isolde revival, director Christof Loy, music director Antonio Pappano and soprano Nina Stemme mooted possibly the toughest role challenge of them all, that of Strauss and Hofmannsthal’s vengeful obsessive Elektra. Yet nearly a decade is a long time in the life of a dramatic soprano, and on last night’s evidence, it's come too late in London.

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.
