Many of the works in this exhibition are as slippery as the title suggests: Raoul de Keyser and Neal Tait's fragmented, nearly abstract paintings; Isa Genzken’s freestanding concrete frames; Andreas Slominski’s steel tube in which, if you crouch down low enough, you’ll find a packet of chewing gum.
Miroslaw Balka, meanwhile, is the most elusive of all in this show of 14 artists.
