Believe it or not, Maybelle Carter's first ever concerts for a folk audience, at the Ash Grove in L.A., are available on the web. And if that isn't remarkable enough, she's even got Mike Seeger backing her up.
It was the New Lost City Ramblers who persuaded Maybelle to do the concerts. They brought her to the Newport Folk Festival soon afterward, thus launching her late career in the folk revival.
The concerts are amazing. She plays autoharp, banjo and guitar. For me, it's a thrill just to hear her speak her introductions.
Can hardly believe what's on the web. Had to share this one.
