Narrated by legendary multimedia artist Laurie Anderson, Lisa Rovner’s superb Sisters with Transistors showcases the music of and rare interviews with female electronic pioneers Clara Rockmore, Delia Derbyshire, Daphne Oram, Éliane Radigue, Maryanne Amacher, Bebe Barron, Suzanne Ciani, Pauline Oliveros, Laurie Spiegel, and Wendy Carlos.

As Rovner’s documentary demonstrates, these women—many of whom were classically trained musicians, brilliant mathematicians, or a combination of both—relished the freedom of electronic music, even as they were discriminated against because of their gender and because of their chosen medium. Through their inventiveness and rebellion, these trailblazers’ music went on to influence musicians working in a variety of genres, and proved the worthiness of going electric.

Sisters with Transistors is an essential primer for those interested in discovering this vital, oft-overlooked history but also offers plenty of pleasures for crate-digging experimental music obsessives who know the BBC Radiophonic Workshop’s output like the back of their hand. Contemporary musicians, such as Holly Herndon and Kim Gordon, also offer insights into their forebears’ indelible music and their personal significance.
