Slipknot had to halt their show in Phoenix Tuesday night for about 30 minutes due to a huge fire on the lawn of the Ak-Chin Pavilion.
Fans started a bonfire on the back of the lawn during "All Out Life" using a huge pile of lawn chairs, and other fans threw their own chairs in as the blaze went higher and higher in the air. After the song was done, the band left the stage and allowed authorities to put out the fire before returning for three more songs.
The delay forced the band to cut two songs, "Duality" and "Spit It Out," that have usually been in their set on this tour.
(Note: you will hear some occasional cursing in the video of the fire that's posted below.)
