The Rockharz Open Air is a metal festival and has been held annually since 1994 on the Harz. It started with around 100 visitors and gigs on truck trailers. Since then, it has become a fixture in the annual Metal Festival Plan. In 2013, around 12,000 visitors were counted. The festival site is the airfield Ballenstedt.
A special feature of the Rockharz Open Air are the two equivalent stages, referred to as Rock Stage and Dark Stage, which can only be found on a few other festival of this kind in Germany. In addition, there is no time overlap between the band performances, so that it is actually possible for the visitors to see every band performance.
