The 2015 Rockstar Energy Drink Mayhem Festival kicks off in Chula Vista, CA today. Normally, a festival like this is nothing to talk about, but the King himself will be performing this year! No, I don’t mean Elvis. I’m not even referring to Slayer’s Kerry King, who is also a part of the fest. I’m talking about King Diamond! Easily one of the best live performances in heavy metal, and after a long streak of either no shows, or shows outside of the U.S, he’s back! If you missed him last October, do NOT make the same mistake again. Get your ass to one of the shows! In the rare chance you need to know more about the 2015 Rockstar Energy Drink Mayhem Festival, other than King Diamond is performing, head on over to http://rockstarmayhemfest.com/.
