The first version of the festival was held in Olofström, with nine bands performing. The next five years, the festival was held in Karlshamn, but this was changed in 1998. Since then the festival has been held in Norje, outside Sölvesborg.
When the festival first began in 1992, it featured nine relatively unknown bands and it only lasted one day. The next year the festival was expanded to two days and more bands were added to the line-up. From 1993 to 2002 the festival would last two days; over those years it would also begin to feature bigger name acts. In 2000 the festival was expanded to three days but it returned to two days the following year.
From 2003 to 2006 the festival lasted three days and had by then featured some of the biggest acts in metal and rock. From 2007 the festival has been expanded to four days and will feature approximately 120 different bands/artists.
