Summer group exhibition round-up III. Summer shows, like summer reading, are supposed to be fun! At David Zwirner visitors are encouraged to sit on, play with, and touch two of Franz West’s installations which form the backbone of a group of works that loosely deal with body/object relationships and include art by Alex Da Corte, Jonathas de Andrade, Felix Gonzalez-Torres, Jonah Groeneboer, Gordon Hall, Hannah Levy, Donald Moffett, Paulo Nazareth, Elle Pérez, Oren Pinhassi, Christina Quarles, Paul Mpagi Sepuya, and Wolfgang Tillmans. Be forewarned, though – the art works come with specific instructions: Feel free to sit on the chairs. Please do not touch the sculpture. But by all means – have fun! But not too much, as the cold glare of the security guard suggests. Those chairs that you are sitting on still need to find a billionaire’s home. At David Zwirner through August 3.
