The Renwick Gallery in Washington, D.C., is exploring the art of the yearly Burning Man event held in Nevada. The show, No Spectators: The Art of Burning Man, opened March 30. The Renwick is part of the Smithsonian American Art Museum. Every August, a temporary city rises from the dust in northwestern Nevada’s Black Rock Desert. As many as 75,000 people gather for the eight-day event called Burning Man. They sculpt, build, perform and invent in many ways while there. Organizers have called Burning Man a crucible of creativity. The attendees are called Burners. Each attendee is equal part observer and actor at Burning Man.
