Lead Belly - Where Did You Sleep Last Night

«"In the Pines", also known as "Black Girl" and "Where Did You Sleep Last Night", is a traditional American folk song which dates back to at least the 1870s, and is believed to be Southern Appalachian in origin. The identity of the song's author is unknown, but it has been recorded by many artists in numerous genres. Traditionally, it is most often associated with the American blues musician Lead Belly, who recorded several versions in the 1940s, as well as the American bluegrass musician Bill Monroe, who helped popularize the song (in a different variant, featuring lyrics about a train) among bluegrass and country audiences with his versions recorded in the 1940s and 1950s.»
