During the folk boom of the late '50s and early '60s, the New Lost City Ramblers introduced audiences to the authentic string band sound of the 1920s and '30s, in the process educating a generation that had never heard this uniquely American sound of old-time music. While maintaining music with a social conscience, they added guts and reality to the folk movement, performing with humor and obvious reverence for the music. In 1958, Mike Seeger, John Cohen, and Tom Paley modeled their band after groups like the Skillet Lickers, the Fruit Jar Drinkers, and the Aristocratic Pigs, choosing a name in keeping with the past. When Tracy Schwarz replaced Paley in 1962, the NLCR added solo songs from the Appalachian folk repertoire, religious and secular, educating a large segment of the American population about traditional music. Folkways recorded the NLCR on five albums in the early '60s, making the Ramblers famous and leading to TV appearances, successful tours, and appearances at the Newport Folk Festival. A songbook with 125 of their songs came out in 1964 and sold well.
