Over the weekend, System Of A Down performed an eclectic set of fan-favorites to a massive crowd at Riot Fest Chicago. The immense mass of people, however, proved detrimental to a select few. The band stopped playing multiple times in order for injured fans to be removed from danger and receive medical attention.

Steve Schneider, an aspiring pro wrestler who was in attendance during the band’s performance, was knocked to the ground and nearly trampled by fans. “I fell over during System Of A down, then someone fell on top of me so I couldn’t breathe,” he said in an exclusive statement to Wrestle Zone. “Then once they got up, someone else fell on top of me. It was never ending. At one point I had someone on top of my back, and someone either sitting or standing on my head, pushing my face down into mud. I couldn’t breathe the entire time, but then any breath I could take I was close to inhaling muddy water. It was the scariest thing in my entire life ‘cause I had no idea how long I’d be trapped for. Apparently System of a Down had to stop playing so paramedics could get me out, I was unconscious at that point, so I have no memory of it. Both of my eyes are blood red from passing out due to lack of air, someone crushing my head [and] screaming for my life.”
