Kevin Costner and his country band were set to walk on stage at a Canadian music festival when it collapsed, killing one and injuring as many as 40 after a powerful storm swooped in and forced thousands to run for cover.
Fans began to scream as a storm with hurricane-level winds showered marble-sized hail on the thousands in attendance at the Big Valley Jamboree near Edmonton, Alberta, last night, according to Canadian television station CTV.

"It felt like bombs were going off around us in this concrete and steel building, Huge hits of power hitting the building, and then the lights were off," country music singer Jessie Ferrell told CTV News.
"Lightening, hail, thunder ... it looked like a tornado," she said. "Debris was flying everywhere."
