The official Mayhem Fest 2013 Survey is out: http://ow.ly/bYAvV
Apparently John Reese uses the survey to book mid level acts on the festival. He stated Unearth would not have been booked the last time they played if not for support via this survey. I wrote in my preferrences of Down, Ghost, Danzig (could play in Anthrax's slot), Arch Enemy & Skeletonwitch.
Mayhem Fest 2012 has barely started so lets save discussion for 2013 until at least Thanksgiving. Just thought I would pass that along.
