The 2011 Venice Biennale opens this Saturday in Venice, Italy. Representing the United States at this year’s show are Philadelphia-born Jennifer Allora and Cuban-born Guillermo Calzadilla. The duo currently live and work in San Juan, Puerto Rico and have been making art together since 1995. This marks the first year that the United States will be represented by a collaborative artist team. Allora and Calzadilla’s work consists of sculpture, performance art, photography, sound and video work that explores historical, cultural and political ideas and the associations between an object and its meaning.
