Helter Skelter: L.A. Art in the 1990s, a 1992 exhibition focused on the dark side of contemporary life[20] as portrayed by artists like Mike Kelley, Paul McCarthy and Chris Burden,[21] involving themes such as alienation, dispossession, and violence. Out of Actions: Between Performance and the Object, 1949-1979, a landmark historical survey presented in 1998, tracked the work of about 150 artists and collectives for whom public performances, in its links to painting, sculpture, dance and theater,[21] and the creative process were far more important than well-crafted objects. Public Offerings, in 2001, explored the phenomenon of youthful creative energy in an overheated art world where stars are created before they leave art school.
