Bill Graham's Day on the Green concerts were the first prototypes of "festival" shows - multi performer sets in stadium settings. Staged on the lawn of the Oakland Coliseum, the Day on the Green concerts were a summer series started in 1973 that continued until shortly after Graham's death in 1991.
"That was why I came up with the name "Day on the Green". I wanted to make these events special. I wanted to create giant outdoor sets so the bands would be going into a space that was like a theater piece." -Bill Graham
