The Who concert disaster was a crowd disaster that occurred on December 3, 1979, when the English rock band the Who performed at Riverfront Coliseum in Cincinnati, Ohio, United States, and a rush of concert-goers outside the Coliseum's entry doors resulted in the deaths of 11 people.

A stampede is a situation in which a group of large animals suddenly start running in the same direction, especially because they are excited or frightened. Although the term is most often applied to animals, there are cases of humans stampeding from danger too.

The Who are an English rock band formed in London in 1964. Their classic lineup (1964–1978) consisted of lead vocalist Roger Daltrey, guitarist Pete Townshend, bassist John Entwistle and drummer Keith Moon. Considered one of the most influential rock bands of the 20th century, their contributions to rock music include the development of the Marshall stack, large public address systems, the use of synthesizers, Entwistle's and Moon's influential playing styles, Townshend's feedback and power chord guitar technique, and the development of the rock opera. They are cited as an influence by many hard rock, punk, power pop and mod bands. The Who were inducted into the Rock and Roll Hall of Fame in 1990.
