Of all the destructive Guns N' Roses moments, it's pretty clear none were as damaging or terrifying as the August 1992 riot sparked when the band cut a show in Montreal short.

GN'R were in the middle of a co-headlining tour with Metallica, and tragedy had already struck that group earlier in the evening when singer James Hetfield was badly burned in a pyrotechnics mishap, forcing them to cut their set short. When Axl Rose was forced to end his group's performance after less than an hour due to vocal problems, many in the crowd, well... lost their minds. Windows were smashed, cars overturned, fires started and a street lamp was even uprooted. Three hundred cops had to be called in to get things back in control again.
