As the profile of the arts-and-health sector grows and interdisciplinary projects with public outcomes become more common, it is useful to explore roles and ways of working at the interface between different disciplines. The authors analyze the complex role of producer, likely to become increasingly relevant in this landscape. While incorporating aspects of existing roles (e.g. hospital arts manager, cultural venue participatory producer, independent creative producer, public engagement manager), the producer has a very specific raison d'être and could be defined as “relational producer.” This role is not well understood and yet central to this field of practice.
