Gwen Foster is something of a mystery. The hard-drinking harmonica wizzard first came onto the scene in 1925, when he made his first recordings with the Blue Ridge Entertainers. He later joined the Carolina Tar Heels along with Doc Walsh and Clarence "Tom" Ashley, recording various tracks for Victor. In the early 1930s, he cut some duets with Clarence Ashley, but then vanished from the music scene, apart from two last recordings with Doc Walsh in 1932. Joe Joe Filisko credited Foster in "Back to the Roots" with being "the hardest to imitate and being one of the more orioginal unique harmonica players that ever played." Nobody knows what happened to Foster after 1932.
Here are two of his solo recordings and one with Clarence Ashley:
1. Black Pine Waltz
2. Wilkes County Blues
3. My Sweet Farm Girl (with Clarence Ashley on vocals and guitar)
