Nine festival-goers died as the crowd surged forward on a muddy farm field during a Pearl Jam concert. Twenty-six people were injured, three of them seriously. Of the fans that died, one was a 26-year-old cadet police officer from Hamburg, one was a 23-year-old Dutchman and three were from Sweden, two of them aged 22 and one 20. Three Danes, including a 17-year-old, also died. Their different nationalities reflect the festival's huge international diversity.
