In discussion with Emily Sexton, we hear from three artists whose creative work veers close to boundaries – whether death, censorship, trust or the base conditions of our existence. D.A. Calf is a theatremaker with The Guerrilla Museum, whose immersive live art has looked closely at death. Scott Price is an actor and a key deviser with Back to Back Theatre with a well-known penchant for provocation. And Jessica Thom has blogged extensively about her life with Tourette’s – at her website, you can cast ‘funny votes’ for almost 6,000 of her tics – while, as alter ego Touretteshero, sharing the creative, playful side of the often misunderstood condition.
