This smackdown is perhaps the most infamous “musician vs. crowd member” moment of all time. During the middle of a St. Louis Guns N' Roses concert in 1991, frontman Axl Rose dove into the crowd to confiscate a camera from a fan. After delivering a right hook, Rose jumped back onstage and said, “Well, thanks to the lame-ass security, I'm going home.” The actions of Axl Rose led to what is now known as the “Riverport Riot.” Fans broke out into violence and destroyed Guns N' Roses' equipment, which Rose claimed to have been worth one million dollars.
