Musician Wendy Carlos wrote the score to Stanley Kubrick‘s “A Clockwork Orange,” “The Shining,” Disney’s “Tron” and helped popularize the Moog synthesizer in the 1960s and 1970s. Clara Rockmore helped popularize the otherworldly theremin instrument in the 1960s, but both figures are essentially still just obscure cult figures in music. That’s hopefully going to change a little bit with “Sisters With Transistors,” a new documentary about the female pioneers in electronic music whose radical 20th-century experiments redefined the boundaries of music.
