Safety above all
During the 80s, safety was a point of particular interest. The Heysel (1985) and Sheffield (1989) stadium disasters had made governments extremely nervous. During its history, the festival has been spared of major irregularities. And whenever things went a bit wrong, it occurred outside the festival ground. There are many reasons for this success: correct assessment of the audience, sang-froid and never-ending security efforts. By using rubber mats and pressure-reducing constructions – the famous St Andrews cross – turmoil in front of the stage is avoided. In 2004, the phenomenon was reversed: the audience was worried about the safety of a band. The amount of pyro Rammstein had brought on stage kind of equalled the yearly amount of stadium fireworks used by RSCA Anderlecht, a Belgian football team.
