GSK Contemporary

Once again, apocalypse comes to the RA. And of the three shows that comprise 'Collision Course' – the second part of the GSK Contemporary strand – 'Sudden White (After London)' detains one most. Ryan Gander celebrates his millionth show of the year, Mungo Thompson's darkly comic collation of landscape sequences from 'Roadrunner' rises above the dandyish mood of doom, and a film of Robert Smithson visiting California's Mono Lake – featuring rock-collecting, musical interludes by Waylon Jennings, and maps wiped with marshmallow before being burnt – provides a skewed highlight.
