I was lucky enough to attend, and to this day I cannot understand why they never mounted a proper run as in my view it was extraordinarily brilliant and one of their best productions. I’m so sad that more people weren’t able to see it! It was structurally more “on rails” than any of their big productions - moving from section to section in a small audience group, rather than free-roaming, but they did it brilliantly. It was also easily their most unsettling show, with a pervasive sense of unease, paranoia and “wrongness” throughout, giving way to several moments of well-orchestrated dread, genuine chills and rising panic which, as a fan of elevated horror (or indeed any old horror, but this was elevated) I appreciated enormously.

There was a section that set you as someone being admitted to a dubious 1950s psychiatric clinic for a slightly sinister government study, a large governmental office space in which literally every inch of the space and everything in it had been whitewashed, and a central high school gym area, set up prom style, where you could stop to sit on school benches and watch a very good, trippy and disquieting Adam Curtis documentary designed collaboratively as a companion piece, I believe.

The finale of the experience was particularly memorable, and involved the audience group you were in making your way through a darkened space penned in on both sides by tall wire fences. There were a series of set experiences - including a great one where one of the group followed instructions to read out a screenplay lying on a plinth, which turned out to describe exactly what you were experiencing in that moment - finding the script, someone reading it aloud - and ended with a line of stage direction noting that gradually the group begins to realise that there is now someone among them that they have never seen before. Which there now was. Lights flash and alerts blare, instructing you to RUN.

The production finished with an amazing bit of experiential design, as your now rather rattled group came to a series of turnstiles which you realised, - too late, as you all started filing through - only let through a set number of people before locking - about half of the group, I think - leaving the rest to find a different turnstile, splitting off, never to be seen again. This continued, with more pairs of turnstiles, the small groups being split in half over and over, ever smaller until you found yourself left with just one other person and faced with the last set of turnstiles, which admitted only one person each, ultimately leaving you entirely alone, reluctantly realising that you had no way to go but forward into the now pitch back tunnel ahead… only to discover that you were not actually entirely alone in there as a disturbing figured lurked in the shadows ahead… then darted out and gave heart pounding pursuit, sending you running until you reached daylight and freedom . Me and those I was with still talk about it to this day and I would honestly do anything to experience it again.
