First year? Don't worry about getting involved in a camp. If you find one great. More important is to be self reliant. Camp by yourself or with friends you KNOW. Bring your instrument and travel around. Centercamp is a great space to play out. You can play ANYWHERE ANYTIME. You will find your crowd soon enough. Or your crowd will find you.
The only musicians I know is EE Marching Band (Environmental Encrochment). You might fit in with their jam, you might not. They're out of Chicago.
Most importantly you need to understand is bring no expectations. It takes less time to explore the hot spots of Chicago, NY, London and LA then it does to explore half of Black Rock City.
You'll find folks to play with, no doubt. Just go and play. The rest will materialize in front of your eyes without you even knowing it.
