This fourth public discussion based on APG’s discursive format The Sculpture looks at the complex and often problematic position of John Latham within APG. His 'time-based' theories according to which space and objects are displaced by time and events, played a significant role in how APG identified itself and defined his work on placement with the Scottish Office and the National Coal Board. His re-configuration of the artist as an 'incidental person' led to conflict amongst the Group's members. This discussion – moderated by Claire Louise Staunton (Director of Flat Time House) with participants including Clive Phillpot, Gavin Wade, Antony Hudek and Barbara Steveni – consider to what extent Latham's work and ideas have come to shape what we know as APG.
