Dust-to-Digital proudly inaugurates its vinyl imprint Parlortone
with the earliest intelligible recording of the human voice: an
historic 20-second version of Au Clair de la Lune made in 1860, 17
years before Edison invented the phonograph. This one-sided 45rpm
record comes complete with an etched back, a descriptive essay and a
reproduction of Édouard-Léon Scott de Martinvilles original Au Clair
phonautogram.
