Most music historians trace country's two main strands to its first superstars: blue yodeler Jimmie Rodgers, and balladeers the Carter Family. Their classic repertoire, haunting vocal harmonies, and Maybelle's distinctive guitar style have kept their old-time music relevant and moving to the modern day. The original group broke up in 1943, and the name was adapted by one member (Mother Maybelle) and her three daughters (June Carter Cash among them), and various combination of Carters performed and recorded in the '50s and '60s.
