Groovy, Man!

Sound was first
recorded in the grooves of a rotating cylinder in 1877, and discs
about ten years later. In the mid-1920s, we began to amplify the sound
electronically for recording and for playback.
Although grooves can be worn down by frequent
use, some early shellac discs have survived 100 years! With
proper care, vinyl records should last even longer.
