Think of early electronic music and you’ll likely see men pushing buttons, knobs, and boundaries.

As one of the film’s subjects, Laurie Spiegel explains: “We women were especially drawn to electronic music when the possibility of a woman composing was in itself controversial. Electronics let us make music that could be heard by others without having to be taken seriously by the male-dominated establishment.”
