The Who will return to play in Cincinnati for the first time since 1979. A stampede to get into the show left 11 people dead. Shockingly, the band didn't know what happened before the show and the only found out later. They have a lot of regrets about how the incident was handled and Pete Townsend and Roger Daltry open up for the first time on dealing with the grief. Before this incident most concerts were general admission so this event really did change the world of rock.
