Here's the website:
http://www.shambhalamusicfestival.com. Go. You'll love it- it's not like any other party out there. Even if you are just getting in to this kind of music, you'll have so much fun- it's about more than the music.
A couple of the bigger names are Adam Freeland and Freq Nasty, but really, with 5 stages, you'll always find something you like, and the bookers do an excellent job at bringing in really good talent that you may not have heard of.
