We discuss the tragic events that unfolded at the Astroworld Festival 11/5/21 & explain how an incident action plan works, the command post set up, the crowd grid & how the medical assignments work, the chain of command, the kill switch, & how this all has to work together to prevent these tragedies. We talk about how and why crowd crushes and surges happen, including ones that we've experienced as concert goers. We get a lesson on the history of music festivals and raves in LA, & discuss how we had to stop the show at our own rap festival, Camp Flog Gnaw, for 45 minutes during a Post Malone performance to stop the crowd surge. We talk about what could've gone wrong at Astroworld & how this can be prevented in the future, & who bears what responsibility. You also learn how people die in these situations and exactly what a human crush injury is & how it happens.
