In subsequent years, too, most of the tasks were carried out by the small team. Until August 1994, for example, ticket orders were organised privately by Andy Göser's mother Regina Göser and security duties were performed by friendly motorcycle clubs up until 1996. In 1991, the number of visitors increased to 1.300, and with Skyline returning, Bon Scott, an AC/DC cover band from Hamburg, Gypsy Kyss, Kilgore, Life Artist, Ruby Red, and Shanghai'd Guts joined them on stage for an all-regional roster. That same year, the iconic skull logo was designed by Mark Ramsauer after the basic shape had been determined by Thomas Jensen and Holger Hübner. The cow skull refers to the venue, a meadow for cows, and to Jensen and Hübner as "boys from the village".
