A stage under construction for a Radiohead concert in Toronto collapsed today, killing one person and injuring at least three, the Globe & Mail reports. Workers were hanging screens on the stage when it fell, according to a beer tent worker: "Apparently the band was supposed to practice just before [the collapse]," she said. Cries of "First aid!" emerged from the stage, and security began removing a considerable crowd that had gathered early for the concert, the Toronto Star reports. The sold-out show has been canceled.
