John Kane is sitting on a hospital gurney, and very shortly a jazz percussionist, two women called Mary, a very old man and a giant lobster will arrive.

Then everything will start.

Medicine is a dark and frequently absurdist work that shatters the boundary between cast and audience. It is a devastatingly funny and moving meditation on how, for decades, we have treated those we have called ‘mentally ill’.

This production features a sensational cast – Clare Barrett, Aoife Duffin and Domhnall Gleeson, with drummer, Seán Carpio, – as Enda Walsh once again shines a light on the darkest corners of our collective stories. Walsh returns with his regular team of world–class collaborators: designers Jamie Vartan [set], Adam Silverman [lighting], Helen Atkinson [sound], Joan O’Clery [costume] and composer Teho Teardo, with live drumming composed and performed by Seán Carpio.


Running Time | 90 minutes (no interval)
