I am listening to the Carter Family for the first time in my life, I sheepishly admit.
The CD is Best of the Best. Very good, of course. it reminds me a bit of Woody Guthrie crossed with The Weavers, which if I had never heard the Carter Family I would have thought would have sounded like The Weavers.
Right off the first 3 or 4 listens the tunes that are catching my ear are, "Can the Circle By Unbroken", and "Lulu Walls".
