The film maps a new history of electronic music through the visionary women whose radical experimentations with machines redefined the boundaries of music, including Clara Rockmore, Daphne Oram, Bebe Barron, Pauline Oliveros, Delia Derbyshire, Maryanne Amacher, Eliane Radigue, Suzanne Ciani, and Laurie Spiegel.

The documentary is voice by Laurie Anderson and brings together archival footage, interviews and long periods of letting the music speak for itself.
