The latest production from playwright Bess Wohl blends the present and the past to examine the Women's Lib movement in the 1970s. "Liberation" stars Susannah Flood as Lizzie, a woman who, to better understand her mother's past, embodies her mother to witness how she started a consciousness raising group with other women in her Ohio community. One of those women is Celeste, played by Kristolyn Lloyd, a Radcliffe-educated student who has her own thoughts on what it means to achieve liberation. Wohl, Flood, and Lloyd discuss the show, running now at the Laura Pels Theatre through March 30.
