Art: Katharina Grosse's eye-popping installation takes over Brooklyn park

German artist Katharina Grosse has an obsession with scale. She told as much when we spoke to her for the autumn issue of Printed Pages magazine, an interview in which she revealed she goes surfing in New Zealand every year to reset her own sense of her place against the infinite natural scale. All this puts her latest project in a Brooklyn Park into perspective (in every sense of the word). Just Two Of Us is a series of massive multi-coloured sculptures which have taken over the MetroTech Commons plaza, looking like the architectural remains of a post-punk psychedelic society. It’s bright, bold and inescapably interactive; three things Katharina does as well as any artist we can think of.
