January 20 is the birthday of Huddie Ledbetter, better known as Lead Belly (c. 1888–1949). We’re celebrating with a new social media series, “Lead Belly: Song by Song,” in anticipation of the February 24 release of Lead Belly: The Smithsonian Folkways Collection. Find more on our Facebook and Tumblr pages, and listen to a previously unreleased song, “Princess Elizabeth,” which premiered on Rolling Stone.
