The British rock band Radiohead cancelled a concert after their stage collapsed killing one person and seriously injuring another.
The show in Toronto, Canada, was scrapped after the incident, which happened as the stage was being set up.
The band, from Oxfordshire, England, said tickets for the sell-out Downsview Park performance would be refunded.
A statement on the band's website said: "Due to unforeseen circumstances the Radiohead show at Downsview Park tonight has been cancelled.
"Fans are advised not to make their way to the venue. Refunds will be made at point of purchase. Further information is to follow."
Toronto Police posted the news on their Twitter page and asked people to stay away from the area.
In another message, police said: "We are not confirming the number or nature of injures at this time at #Downsview Park. We will provide that later when all facts are in."
One picture posted on the website showed the collapsed scaffolding of the stage.
