20 November 2012 | 7 pm. A special one-off event with architectural historian, Kirsten McKee and architect, Malcolm Fraser coinciding with Collective's exhibition, Adaptation. Kirsten completed her PhD thesis on the landscape, politics, architecture, social organisation and culture of Calton Hill and its environs throughout history. This research is informing Collective's future plans. Malcolm is Director and founder of Malcolm Fraser Architects who are currently developing an architectural master plan for the long-term development of the City Observatory on Calton Hill for Collective. Kirsten will draw on her extensive knowledge of the history and architecture of Calton Hill to introduce and contextualise Collective's new location and its varied history. Malcolm will reflect on his previous experience of working with cultural organisations and redeveloping historic buildings to consider how this new location might impact on Collective's identity, and how such a dramatic change could develop the ambition of the programme. Adaptation was a phased, year-long research project initiated by Sarah Tripp with Collective. The project considers the effect that change can have on form and content - which is particularly pertinent at this time when the gallery is in its own process of adaptation. Duration 1 hour 22 minutes.

Interpretation by Blood Tears & The Moral Highground feat. Jim Colquhoun & Andy Hopkins As one element of his contribution to New Work Scotland Programme 2011 Oliver Braid is working alongside a variety of sound and music makers to produce new audio works in response to a set score. The original score takes the form of an undignified Skype conversation between Oliver Braid and a friend which presents an argument around the concept of expectation. This argument also inspired Oliver’s other contributions to the programme this year, ‘I’ll Look Forward To It: A Visual Essay on Expectation’, his design for the 2011 Christmas Window at Collective and a live music event taking place at Collective on 15th December. PLEASE BE AWARE THIS SOUND PIECE CONTAINS STRONG LANGUAGE
