Roskilde Festival Stage Collapse (2000)

Among the deadliest crowd disasters at a European music festival, the 2000 Roskilde Festival crush killed nine people and injured 26 during a surge toward the stage at Pearl Jam's set. Rain had left the ground slippery, and when fans fell in the dense crowd, security could not see or reach them in time; the band stopped playing and pleaded with the crowd to step back, but it was already too late. In response, Roskilde overhauled its crowd-safety measures, and a safety network of European festivals was set up so the lessons would spread. Pearl Jam cancelled the two remaining dates of the tour, and band members later admitted they had contemplated quitting altogether, underscoring how quickly a crowd surge can turn deadly.
