In 1998, Matthew Shepard was abducted, brutally beaten and left to die, lashed to a fence in Laramie, Wyo. At the time, a group of actors with the Tectonic Theater Project traveled to the town to interview its residents about the tragedy. From those 200 interviews they created the watershed play “The Laramie Project,” which has become one of the most performed plays in America today.

A decade later, Tectonic returned to Laramie and spoke to the same residents to get their long-term perspectives. What the people of Laramie remembered, learned and memorialized about the Shepard incident informed a new play called “The Laramie Project: Ten Years Later,” an epilogue to the original. Both productions will be performed in the Zellerbach Theatre at the Annenberg Center for the Performing Arts, 3680 Walnut St. On Nov. 11, at 7 p.m., Tectonic performs “The Laramie Project”; on Nov. 12, at 8 p.m., they perform “The Laramie Project: Ten Years Later.” Visitors can also see both on the same day: Nov. 13, “The Laramie Project” runs at 2 p.m. and “The Laramie Project: Ten Years Later” shows at 8 p.m. Ticket prices range from $20-$50.
