The impact calculator is a one-to-one performance presented during Always Already: Impact and the Everyday, a symposium organised by the CCPRG @ University of Sussex.

This music theatre experiment has a sarcastic attitude toward the key subject of the symposium: the measurement of Arts’ social impact. It aims to playfully blur the borders between the roles of performer and audience; offering a single member of the audience to be in a situation that requires their own contribution for the development of the performance.

The impact calculator is one of the experiments of a larger scale practice-based research on interactive music theatre.
