Het concert van System Of A Down in Chicago tijdens Riotfest moest enkele malen stil worden gelegd omdat er enkele gewonden zijn gevallen tijdens de show. Een van de breaks in de set duurde wel 15 min.
Worstelaar Steve Schneider getuigde op de website Wrestlezone.com hoe erg de situatie wel was.
"I fell over during System Of A Down, then someone fell on top of me so I couldn’t breathe. 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 ’cos 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 and someone crushing my head and screaming for my life."
Gemaakte fanbeelden tijdens de show geven een beeld van wat er aan de gang was. De groep kon een half nummer spelen voor ze opnieuw gevraagd werden te stoppen. Serj Tankain zei on stage dit: "It’s extremely awkward to sing when there are people who look like they’re dying right in front of me".
