Slipknot Stopping a Concert in 2019 At a Slipknot concert in California in 2019, singer Corey Taylor stopped the show when he saw fans getting crushed in the pit section of the arena. "Are you all right?" he asked, halting the concert until fans agreed to back up and make more room for each other. "I'm not starting this song until you motherf*ckers back up. We are all here together, so back the f*ck up!" Once the audience complied, the concert resumed. Image Source: Getty / Ollie Millington
