OVO is the "soundtrack" to the Millenium Dome show. The show tells the story of three generations of family. While the story is outwardly about the struggles of a family in times of change, it is more accurately described as being a "fable" whose subject is the society and world we live in. Peter Gabriel described the theme in a press conference for the release of OVO:
"The idea is that each ideology is like a season: summer follows spring, then autumn, then winter... If something is to be born something else has to die. We tried to illustrate this idea setting the story through three generations of one family, where the father represents the agricultural, the son is the industrial, and the newborn is the post-industrial economies and societies."
