Mark Smith talks to artist and performance maker Ellie Harrison about her interactive installation work The Unfair. This is part of her ambitious long-running project The Grief Series, which aims to offer playful and open artistic environments for the contemplation of taboo subjects such as loss and grief in many forms. The Unfair examines the anger which might be associated with a range of such experiences, and gives visitors an opportunity to vent their frustrations through fun and games which play humorously upon vintage fairground imagery. There's popcorn, Angry Jenga, and a karaoke booth complete with punchbag so you can box your way through your choice of anger-releasing song. The Unfair runs at Kirkstall Abbey, Leeds, from 9-14 May. Entrance is free. It then runs at the Brighton Festival from 18-21 May. Entrance is pay what you feel.
