Sharon Irish's book on Stephen Willats pulls together key strands of his practice and threads them through histories of British cybernetics, experimental art, and urban design. For Willats, a cluster of concepts about control and feedback within living and machine systems (cybernetics) offered a new means to make art relevant. For decades, Willats has built relationships through art with people in tower blocks, underground punk clubs, middle-class enclaves like Harrow, and warehouses on the Isle of Dogs, to investigate their current conditions and future possibilities. Irish's study demonstrates the power of Willats' multi-media art to catalyze communication among participants and to upend ideas about `audience' and `art.' Here, Irish argues that it is artists like Willats who are now the instigators of social transformation.
