As British Petroleum’s Deepwater Horizon oil rig spewed enough crude into the Gulf of Mexico to be seen from space in late April 2010, the Tate Britain saw fit to celebrate their long-standing sponsorship by BP at their annual summer party. While oil stuck to shorelines and wildlife, the black mark of ecological destruction failed to stick to BP, at least for that night. Artist-activists Mel Evans and Anna Feigenbaum and the Liberate Tate crew crashed that party with performance art protesting both the polluters and those who associated with them. Now, five years later, Evans revisits the relationship between “Big Oil” and “Big Art” in Artwash: Big Oil and the Arts. Evans accuses Big Oil of focusing more on cleaning up their image than their business’ collateral damage and charges cultural institutions that take Big Oil sponsorship money as accomplices to that crime.
