Scripted by Belfast-born playwright David Ireland, Coldwater is a smart and addictive thriller, which manages to squeeze some fresh twists out of its murderous narrative. It also benefits hugely from an excellent cast firing on all cylinders, while also reaping the benefits of its Scottish rural locations.

Hackney’s Round Chapel is an appropriate venue. Scottish smallpipes player Brìghde Chaimbeul opens her set with “Dùsgadh/Waking.” It has the spirit of a call to prayer: the directness, the insistence, the magnetic quality. All of which draws in anyone exposed to its power. It enchants.

My colleague Boyd Tonkin visited the Lammermuir Festival for the first time this year. His eyes and ears have been opened to its treasures, but some of us have been in on the secret for years. Importantly, that includes the East Lothian audiences, who have been attending the festival in bigger numbers than ever, ensuring that the festival has sold out almost every concert in its biggest venue, St Mary’s Church, Haddington, and packed out many other smaller ones, too. 

How do you tell the story of a person’s mind? In the preface to Electric Spark: The Enigma of Muriel Spark, published this year by Bloomsbury, Frances Wilson points out that biography was one of her subject’s own fixations.

Spark’s first full-length book, Child of Light, reinterpreted the life of Mary Shelley by means of a novel two-part structure: half “Recollection” and half criticism. She went on to write several literary biographies and her fiction is populated by chroniclers, libellers, and legacy-obsessed pensioners.

One piece that you’re unlikely to hear at the Lammermuir Festival is Lucia di Lammermoor. As co-director James Waters explained during a drive to the absurdly picturesque church and castle at Crichton (fit setting for a Netflix epic, let alone a blood-soaked bel canto opera), venues and resources do set some limits to works that can be presented to the standards he demands.

There is such nonchalance with Sabrina Teitelbaum that even her appeals to the crowd appeared laid-back. At points during her set the Los Angeles singer would slowly raise an arm, in the time-honoured tradition of a musician demanding noise, but in a way that suggested she wasn’t bothered if the call was actually heeded. Then again, perhaps it was just a sign that she knew the gesture would have the desired effect, given her evident popularity here.

You wait years for a guitar group with brothers to reunite and then two come along at once. The Maccabees return might have attracted far less attention compared to the Gallaghers hitting the road again as Oasis, but as they strolled onstage on a humid Glasgow night the ecstatic reaction from fans suggested it was a sight many had not expected to see again.

With the sheer density of theatrical creations jostling for attention across Edinburgh’s festivals, there’s no shortage of arresting stagings, innovative visuals and powerful, memorable design. (Just take Cena Brasil Internacional’s shocking Tom at the Farm as one particularly epic, raw example.)
