Patti Smith has taken part in a tribute to the nine people who died during a crowd surge at the Roskilde festival ten years ago.
The festival-goers were crushed to death against an outdoor stage when over 50,000 fans moved forward during a Pearl Jam set in June 2000.
The Associated Press reports that Smith threw nine roses into the audience as musician Lenny Kaye read out the victims' names.
Forty-three people were also injured during the incident in Denmark, which was later blamed on “a chain of unfortunate circumstances”.
This year's festival runs over four days, and will feature the likes of Muse and Kasabian.
Meanwhile, Smith headlined the Serpentine Sessions festival in London on Thursday (July 1).
