Kronos Quartet’s collaboration with composer Jonathan Berger and novelist Harriet Scott Chessman, My Lai revisits the horrors of the massacre and its aftermath from the perspective of the heroic helicopter pilot, Hugh Thompson Jr., who tried to intervene. Join Berger, Chessman, Kronos Quartet’s David Harrington, vocalist Rinde Eckert, instrumentalist Vân-Ành Võ, and Drew Cameron of the Combat Paper Project for a conversation in the Barbro Osher Theater. My Lai will be presented by Cal Performances on Sunday, March 4, at UC Berkeley’s Zellerbach Hall; for information, visit calperformances.org.
