octagon doctor's video: Doctor Reacts Travis Scott Astroworld Injuries

At least eight people are dead and dozens more injured after a sold-out crowd of roughly 50,000 surged during rapper Travis Scott's performance late Friday at the Astroworld Festival outside NRG Park, overwhelming security forces and resulting in one of the deadliest concerts in U.S. history. As Scott's performance started shortly after 9 p.m., the chaotic crowd seemingly swallowed everyone in it, Instagram user SeannaFaith wrote. "The rush of people became tighter and tighter. .. Breathing became something only a few were capable. The rest were crushed or unable to breathe in the thick hot air," she wrote. "It was like watching a Jenga tower topple. Person after person were sucked down.... You were at the mercy of the wave."
