AmericanaFest 2022 is in the books, and even more than usual, I came away with a backlog of fascinating conversations with artists who don’t live in Nashville but who are making an impact on roots music. This week’s show features highlights from three interviews with emerging talent in the veins of traditional old-time, modern bluegrass and folk-rock. There’s no such thing as a representative sample of the format’s younger generation, but between Tray Wellington, Nora Brown and Taylor Rae, there are plenty of storylines that will unfold and develop in the years to come.
