Tufts University Art Galleries celebrates this week’s opening of the exhibition “re:imagining collections” with the debut performance of “Before and After (Object Lesson)” by artist and choreographer NIC Kay.

“Before and After (Object Lesson)” is one of five new commissions by Tufts Art Galleries for “re:imagining collections,” a group exhibition that reconsiders the university’s antiquities collection through the work of contemporary artists Ali Cherri, Nicole Cherubini, Lily Cox-Richard, NIC Kay, and SANGREE. Each artist reconsiders and readdresses the collection of relatively understudied antiquities from the Americas and the Mediterranean to pose new questions about the histories and narratives that extend beyond the objects into the very formation of the collection.

The exhibition will be on view through April 23; gallery hours are 11 a.m. to 5 p.m., Tuesday-Sunday.
