Last month, Dave Mustaine revealed he’s been diagnosed with throat cancer. As fans have been supporting the frontman/guitarist, the majority of Megadeth’s scheduled shows for this year have been cancelled. We’ve already seen the Misfits reunion being added to this year’s Psycho Las Vegas, and now Kreator has replaced Megadeth for Slayer’s final Chile performance. The German thrashers are now part of the bill of the Santiago Gets Louder Festival, which is scheduled for October 6th in Santiago, Chile. Other bands include Anthrax and Chilean extreme metallers Pentagram.
