Want to hear the first advertisement for a soda, recorded a century ago? Now you can

The first audio advertisement for a soda. A vaudeville act about sneezes. A home "exercise tape" from the 1920s, featuring a man giving calisthenics instructions accompanied by an orchestra. One of the first live music performances recorded, a 4,000-person choir in London singing Handel. A 1913 recording where a scoutmaster demonstrates all of the patrol calls used at the time by the Boy Scouts (you will not believe how well this man could imitate a bird).

For the past year, we have been working at our podcast, The World According to Sound, looking to archives like the Library of Congress and the New York Public Library to dig up and curate old recordings like these. We are making an experimental audio show that celebrates sound recordings made before 1923,
