They stand in a row, nine of them, in a long, strange corridor between rows of stacked, palleted, planked wood and the red brick wall of an endless warehouse. Nine tripods, each two humans high, with a spinning helicopter head, double-ended by conical horns that emanate a gentle angelic howling or lower end drone-hums. Eyes closed – and being music-geeky about it – this carefully calibrated tonal concerto assails the ears somewhere between US mystic Laraaji’s processed gong experiments and the final ethereal works of Spacemen 3.

Does a subjective theatre piece encourage a subjective critical response? I think it might, especially when it’s a memory play about dementia, so here goes: first I turn off the lights, then I press play. From the darkness comes jaunty music – it’s a dance class. The teacher says, “We’re not used to having a man in class, are we ladies?

Wowee! Twenty weeks after the last time I set foot in a theatre, I was able to visit a venue once more. Hello again Donmar! It’s great to see you again. Not for a show featuring live performers, who are currently banned, but for a theatre experience in the guise of an art installation, which is allowed.

In just five years, what the team behind Hidden Door Festival has achieved is quite remarkable. Having sprung up in 2014, taking over a group of disused vaults behind Waverley train station, the festival’s mission to transform redundant spaces in Edinburgh has left an immovable, and much needed, creative footprint on the city.

The concluding episode came, and in a confusion of dates I missed it. If you’ve been following the weekly podcast Serial, you, like me and millions of avid listeners, would have been counting the days. I caught up only once I’d read the spoilers, which let it be known that they’d be no neat “did he or didn’t he” conclusion (was anyone actually expecting one?) and that we’d still be left in the realm of “maybe this, maybe that”. How frustrating.
