Update & teaser: Doorways in Time, #6 -- Early Audio Recordings

I update listeners on the podcast's new partnership with a producer, and provide a short clip of the latest patron-only lecture on the rediscovery of the lost early history of sound recording, ranging from French space lasers to a long-lost recording of a German leader singing an American folk song and the "Marseillaise." Special thanks to the First Sounds collective, for recovering long-lost audio recordings and sharing their files freely with the global public, at www.firstsounds.org. All audio files used in this lecture are courtesy of First Sounds, except for the Edison/Wangemann cylinder recording from 1889, which is courtesy of the National Park Service and the Cylinder Archive.
