Helen Kirwan’s immersive three-screen film installation, ‘Grief-Work’, is at the European Cultural Centre in Venice. Showing the artist endlessly walking as a character on a metaphorical journey, the film meditates on loss, memory, time and temporality. It presents a montage of fragmented but interwoven episodes in a repeating structure, and is accompanied by a soundtrack by Tom Lane. Grief-Work: until 27 November
