I particularly loved the coverage of Mother Maybelle Carter and the Carter family, a first family of country music. I'm guessing many young fans of today's country music may never even heard of them. Ken Burns traces the music from it's roots in the "hillbilly" music of the Appalachians, to bluegrass and rockabilly, to the Golden age of country in the 50s and 60s. He doesn't miss a single twist or turn, or any of the iconic artists who created the music from the early 20th century to today.
