As with all of Joz Norris’ previous silly, high-concept Fringe hours over the years, this is another portrayal of an egotistical, attention-seeking idiot. The premise is that tonight, after 30 years of toil and tunnel-vision devotion, Norris is poised to reveal his life’s work. An almighty but secretive undertaking, the character believes himself an auteur genius, despite mangling the names of supposed peers such as Van Gogh and Da Vinci. His wife and child neglected to the point of estrangement, he is nevertheless so giddy, so thrilled by the realisation of his vision that he can’t quite bring himself to fulfil it, masochistically savouring the procrastination and his fantasies of immortality.

While it’s no great spoiler to disclose that Norris may not have split the atom or written The Great American Novel, what impresses is the intricacy and layering of You Wait. Time Passes. In a white martial-arts outfit (implying a misguided Western version of Eastern enlightenment), Norris indulges in a doomed dialogue with his own self-regard, laying waste to the best laid plans of his presentation with escalating manic intensity. There are some lovely, farcical bits of business with his new AI girlfriend. And satisfyingly, the big reveal does not disappoint. 

Joz Norris: You Wait. Time Passes, Pleasance Dome, until 24 August, 7.10pm; main picture: Oliver Holmes.
