This is a book about collaboration in the arts, which explores how working together seems to achieve more than the sum of the parts. It introduces ideas from economics to conceptualize notions of externalities, complementarity, and emergence, and playfully explores collaborative structures such as the swarm, the crowd, the flock, and the network. It uses up-to-date thinking about Wikinomics, Postcapitalism, and Biopolitics, underpinned by ideas from Foucault, Bourriaud, and Hardt and Negri. In a series of thought-provoking case studies, the authors consider creative practices in theatre, music and film. They explore work by artists such as Gob Squad, Eric Whitacre, Dries Verhoeven, Pete Wyer, and Tino Seghal, and encounter both live and online collaborative possibilities in fascinating discussions of Craigslist and crowdfunding at the Edinburgh Festival. What is revealed is that the introduction of Web 2.0 has enabled a new paradigm of artistic practice to emerge, in which participatory encounters, collaboration, and online dialogue become key creative drivers. Written itself as a collaborative project between Karen Savage and Dominic Symonds, this is a strikingly original take on the economics of working together.
