Gotthard, a hard-rock band from Lugano in the Italian part of Switzerland and Bern in the German part, was founded in 1990 by mentor and co songwriter Chris von Rohr, best known as Krokus' bass player. Gotthard is definitely one of the most famous and successful Swiss artists ever and almost every album has topped the Swiss charts since 1990.
These are photos from concerts where Gotthard played, so they may be of other bands that played the concert as well.
