For one week every summer, up to 70,000 revellers gather in the Nevada desert for one of the world’s most far-out festivals.
Wearing anything from neon-coloured tutus, to nothing at all apart from a slick of face paint, they head for Black Rock City, a “temporary metropolis” in the desert, for the Burning Man event.
The aim is for attendees to help “co-create” a huge arts festival, while surrounded by giant interactive art installations and sculptures, such as a 25ft (8m) tall steel coyote, a 30ft-tall spinning wheel, and a temporary ornate temple.
A huge wooden man is then ceremonially burnt towards the end of the event.
With 10 declared key principles, including “radical self-reliance”, “radical inclusion”, and “radical self-expression”, to some outsiders the festival doesn’t so much sound radical, more like a gathering of hippies.
Add the fact that many participants don goggles to guard against the occasional sandstorm, and the event is often described as “Mad Max meets Woodstock”.
