Hi, and welcome to ePlaya. If you're looking at Burning Man simply as a place to promote your work, personally I say fuck off.
If you actually genuinely want to connect with the event, start by taking a look at the wealth of information made available on the main site. Familiarize yourself with the ten principles
(which should explain my earlier comment about wanting to exploit the event for your personal commercial gain), and read the survival guide
. That will help you figure out some of the things you'll need to do to prepare for the journey once you've gotten tickets to the event. For details on ticket sales for next year (all performers are responsible to get their own tickets, as well as making their own arrangements for camping and survival), subscribe to and stay tuned to the Jack Rabbit Speaks
newsletter. Good luck sorting things out.
