Moving Sounds explores the unique animating symbiosis that develops whenever previously unrelated technologies become intertwined and form a mutually invigorating relationship. When "car" and "radio" became permanently inculcated, it changed how both cars and radio were designed and experienced. Moving Sounds is the first book-length study exploring the relationship between the car and the radio. While much scholarship has been devoted to the general history of radio, radio's unique relationship with the open road has been largely overlooked. The nascent interconnectivity between the early car and radio developers, and what they did to help each other, is another aspect of cultural history that is explored in Moving Sounds.
