California kult black metallers, VALDUR, will ravage unsuspecting ears at this year's edition of the Rockstar Energy Drink Mayhem Festival. The band was recently added to the July 10th show at the Shoreline Amphitheater in San Francisco, California where they will systematically level the Jagermeister stage and all those in attendance. Said the band in a collective statement: "We will be more than pleased to take this opportunity to play our extreme metal to unsuspecting people who otherwise may not be familiar with the underground. We got asked to play, we said yes, and we very much appreciate Jagemeister for the invite. Expect a brutalizing set."
