Guadalajara-based artist Gonzalo Lebrija created a public art installation in the parking lot (1430 Delgany Street, Denver, CO 80202) across from the Museum of Contemporary Art Denver (MCA Denver) in the summer of 2010. The installation, entitled History of Suspended Time: Monument for the Impossible, was developed as a dual collaboration with MCA Denver's museum-wide exhibition, Energy Effects: Art & Artifacts from the Landscape of Glorious Excess, as well as Denver's inaugural 2010 Biennial of the Americas, an international event that celebrated the culture, ideas and people of the Western Hemisphere.
