Recorded Sound

Here's something cool to kill time on a Friday afternoon at the office, this site from the National Park Service has the earliest known recorded music in existence. This and the other recordings on this page were originally recorded on an Edison yellow paraffin cylinder, some dating back to 1888! They also have what is thought to be the first recording of Thomas Edison's voice. We sure have some a long way. What would you rather carry around in your backpack, a phonograph cylinder or an MP3 player? Try getting that cylinder through airport security.
