Some verbiage on the topic...

There's tons of information on Burning Man's Official site, www.burningman.com.
You might start with What is Burning Man? (if you're new to all this).
You can read an excellent article written by Burning Man's Art Curator, Christine Kristen aka LadyBee, called 'Reconnecting Art & Life at Burning Man' (originally published in Raw Vision, a journal of 'outsider art').

We have our own very favorite wordsmith, Suzanna, aka 'Bell' on the case for us, creating words for press releases and later, signage, for the show...

Here are some of her early thoughts...

Each year at the end of summer, an immigration unfolds, pointed into the blank white deserts north of Reno, Nevada. This curious caravan is made up of tens of thousands of friends and strangers towing unlikely conglomerations – often called art – out of their garages, studios and back yards, across oceans, highways, and mountain passes to share at Burning Man. The citizens of this temporary city hope for transformation, a wild carnival, or a zen moment of pure expression. What they find when they reach the welcoming gates of this temporary Nevada city known as Black Rock, is the world’s largest art gallery – and the planet’s biggest art installations.

Hundreds of gigantic installations have been featured in the place called Black Rock City in over twenty years of week-long festivals. Everyone who passes these gates is expected to participate. Gifting is a way of life, self reliance and inclusivity are two of the ten principles which keep the city vibrant. The larger works of art at Burning Man are collaboratively produced, bringing many thousands of people out of their workaday realm and into the role of artist.

Producing a gallery show of Burning Man art is a special challenge. The fact is, “burners,” as the participants are known, can only hope to view a small percentage of the vast offerings during the week of the event. The event itself cannot be represented, it can only be experienced. Most installations on the playa are designed to be touched, ridden, climbed, or otherwise engaged. Take a moment to imagine yourself on an unknown planet where at least some of society’s restrictions do not apply, and consider these pieces as part of a playground.

While many pieces of art, large and small, are sacrificed to fire, far more are preserved for new venues around the world. This show brings some of these artistic visions from Burning Man into our community. The pieces you will view in this show withstood the tremendous extremes the playa offers, from 70 mile-an-hour winds to 100+ degree temperatures, along with grinding storms of dust and tiny rocks which can last for days. Remember, the people who offered their works to the citizens of Black Rock City also endured these conditions.
