The Incidental Unit (IU) was formed in 2016 following a series of ‘incidental meetings’, which aimed to informally share information about the APG, as well as its successor O+I (Organisation and Imagination). Founded by artist Barbara Steveni in London in the 1960s, the APG sought to reposition the role of the artist in society. For the APG, the artist was no longer restricted to or defined by the burgeoning culture industry nor conceptual modes of practice. Rather, the artist could be put to work in what was called ‘industry’ in the UK of the 1960s. By way of the APG, artists were placed into governmental and commercial sectors. The IU reprises John Latham’s use of the term ‘incidental’. It is used to refer to activities without a predetermined intention. Incidental also refers to what Barbara Steveni identifies as the ‘not knowing’ experienced by an individual who enters an unfamiliar context or chooses to critically examine their own. The IU encourages approaches that interrupt existing institutional codes and that therefore create the opportunity to develop new patterns in education, administration and planning processes. To this end the IU has no formal organisational structure associated with legal, industrial or cooperative models. It is instead bound together by relations, knowledge, experience and a record of incidental activity that reflects the socially engaged nature of the IU. It is a unit of activity.
