by Tamera H. Bennett U.S. News and World Reports published an article this week on sound recordings that were made 20 years prior to Thomas Edison's invention of the phonograph.
Read the article for a great piece of music and sound recording history about the phonautogram.

(As a side note, one of my favorite scenes in "Oh Brother Where Art Thou?" is when they "cut" the phonograph record. When you watch that scene you understand why the slang is "cut a record.")
