Truth

Vachel Spirason tells us multiple times at the beginning of Truth that he is a “storyteller”. For much of this bonkers 60 minutes, his story makes no sense at all – but trust that it all comes together satisfyingly in the end.

With the invisible help of his co-writer Stephanie Brotchie, Spirason embodies a range of characters to tell us the mad tale of how he came to acquire the plasma globe on stage. These include Juan the Spanish dancer and a sad man in a neck guard looking for potential friends in the audience. But the highlight is his Czech chess champion, whose hilarious “Chessercise” routine has the audience falling off their seats.

Spirason is a fantastic performer who artfully plays with the fourth wall and uses dance, physicality a carefully chosen soundtrack to create an intimate but energetic atmosphere. Truth lacks a little of the heart of The Hermitude of Angus, Ecstatic – Spirason and Brotchie’s hit Fringe show from 2011 - but it’s an accomplished, original work with a striking surreal edge.
