April Tucker, Caroline Losneck, and Christoph Gelfund are the filmmaking team behind LIVING SOUND: A Documenatry About Ethel Gabriel. The film began in early 2019, when April Tucker was researching early women record producers, and discovered an article about Ethel Gabriel–someone she'd never heard of before. Co-directors Caroline and Christoph interviewed Ethel for SoundGirls, an organization that supports women and underrepresented groups in the audio industry.
