While we’re on the subject of how blacks were portrayed by the American mass media at the turn of the century, allow me to direct your attention to Lost Sounds: Blacks and the Birth of the Recording Industry, 1891-1922 (Archeophone, two CDs), an anthology containing fifty-four of the earliest commercial sound recordings made by black performers and public figures.
You can order Lost Sounds here, and you can also listen for free to streaming-audio samples of every track included on the set, including speeches recorded by Booker T. Washington in 1908 and by Jack Johnson in 1910. If, like me, you’re interested in early spoken-word recordings, I guarantee that you’ll find these particular snippets fascinating in the extreme.
