@ Adrian !!
Very late , I answer to your question ! Yes ! Scorpions were over there August 5 th 2011 , under the rain for some of the fans in the pit!
About the concert on August 15 /2013 , It was great!
First band, Rage then Sonata Artica, Gamma Ray, Helloween and Anthrax!
These five groups were given the best of yourselves to satisfy their audience! A perfect harmony! Five hours together of concert in a great atmosphere! Last band "Anthrax " the audience a little exited 'caus the beer certainly ! Were were to the first row, we asked to the security service to pass over the barriers! Jostled from both sides and the fans who came over our heads, we renounce and finished in the terraces ! Anyway! I don't regret this evening! It was great! Thanks to all these groups for this unforgettable evening!!
