Disturbed and Godsmack are ready to lead this year's Rockstar Mayhem Festival tour.  But along with entertaining fans with the music, the trek is also taking steps to help America's veterans.  Disturbed frontman David Draiman is featured in a PSA for Metal Of Honor, which is bringing awareness to the issues returning troops are facing and raising money to help those in need.  The Rockstar Mayhem Festival begins in San Bernardino, California on Saturday, with Machine Head and Dethlok joining the Disturbed and Godsmack on the Rockstar Energy Drink Main Stage, while Trivium is heading up the Jagermeister Stage and Testament caps off the Revolver Stage.  Megadeth will join the tour's main stage lineup with Sunday's show in Mountain View, California, and In Flames will take over as the Revolver Stage headliner in Auburn, Washington on July 12th.  The tour will continue through a stop in West Palm Beach, Florida on August 14th.  More details on each show's lineup and the Metal Of Honor fundraiser are available at the event's website.  RockStarMayhemFest.com.
