My band did this a few months back in California. Its the fest hosted by either Mistress Juliya (Uranium) or Jennifer Arroyo (Ex bassist-Kittie) right? Anyhoo, its just another pay to play fest with a few "big" names to generate some kind of interest in the metal community. The pros: The fests typically draw a large audience because most big local bands are involved and due to the fact that ticket sales determine when your band performs, they are in a friendly race with eachother to draw a larger crowd. Bigger crowd = more networking, so bring demos, business cards, merch, the whole enchilada. The cons: the hosts and staff have literally ZERO interest in any band performing regardless of hype or not. They are there to do their job, they hop on a plane to the next venue and repeat. This also means that the sets generally run about 25 minutes with no setup/breakdown times considered. Make sure to pack light and double check that nothing is left on stage or snagged by another band by mistake. All in all, its a fun gig with a big crowd. Good luck.
