On July 8th, King Diamond performed without his trademark make-up when he hit the stage in Milwaukee, Wisconsin due to an eye infection. It was his first time ever performing without his warpaint. An message from his official Facebook page reads as follows:

"Tonight was the first time ever King Diamond was forced to play a full production show without makeup, due to a severe eye infection. A doctor had, earlier in the day, prescribed medicine and strongly advised against the use of any makeup.

Fortunately there was no negative feedback from this, judging by how absolutely insanely amazing the audience responded to our show. It was so good to be back playing for you all!"

Fan-filmed video from the show can be viewed below, photos are available on Facebook here.

The world's biggest heavy music touring festival, the Rockstar Energy Drink Mayhem Festival enters its eighth year with another fantastic heavy metal and hard rock lineup, featuring 13 bands performing on the Rockstar Energy Drink Main Stage and the Victory Records Stage.

The Rockstar Energy Drink Main Stage features some of the most ground-breaking heavy bands of all time, spanning the originating years of heavy metal to today! The main stage features five-time-nominated, two-time Grammy winning legends Slayer as headliner, as well as additional performances from King Diamond, Hellyeah, and The Devil Wears Prada. The Victory Records Stage will feature headliner Whitechapel as well as Thy Art Is Murder, Jungle Rot, Sister Sin, Sworn In, Shattered Sun, Feed Her To The Sharks, Code Orange and Kissing Candice.

Kerry King, guitarist of Rockstar Energy Drink Main Stage headliners Slayer states, “I don't know if third time will be a charm, but it will definitely be hellish! Slayer and King Diamond on stage for the first time together in the States - NEVER has Mayhem been more evil. DON'T FUCKIN' MISS IT.”

Rockstar Energy Drink Main Stage performer and heavy metal hellion King Diamond states, "This is going to be one hot and hellish summer! Slayer and King Diamond on the same stage - it does not get more devilish than this! We will be putting on a one hour set with the full King Diamond stage production. As for a set list, I'm not gonna reveal that here, but it will be built around "Dreams of Horror". The Puppet Master will be there with Grandma, and we will even go as far back in time as to 1777 (hint). You're all in for one hell of a show if you come to this Sabbath!”

“It has been eight years and it feels like it started just yesterday. We are so excited about this year’s lineup and having the mighty Slayer back in support of a new album. In addition, the first time for King Diamond and Hellyeah will be awesome, as well as The Devil Wears Prada’s first time on the Main Stage. The Victory Stage has amazing bands and will play throughout the day. Heavy music is thriving in America and we are excited to be a part of it,” state John Reese and Kevin Lyman, Rockstar Energy Drink Mayhem Festival producers.

The festival kicked off on June 26 at Sleep Train Amphitheater in San Diego, CA and ends at Gexa Energy Amphitheater in Dallas, TX on August 2. See below for all confirmed tour dates.
