Today marks the 40th anniversary of that tragic night in Cincinnati, when 11 kids died in a stampede at Riverfront Coliseum prior to a concert by The Who. The band was sound-checking and the general admission crowd thought they were starting the show and proceeded to crush through two turnstiles. The event subsequently changed how concert promoters sell tickets and ingress/egress at venues. In a new documentary Pete Townshend says he's still traumatized by that night 40 years later.
