Americana music has been most conspicuously represented in the last few years by songwriting, band-leading artists, including Jason Isbell, Sierra Ferrell, and Billy Strings. Flash back to the origins of the alt-country and Americana movement, and the conversation was more often about bands, such as Son Volt, Whiskeytown, and the Old 97s. Such outfits made well-written roots music that rocked with that collective commitment that makes bandcraft so fascinating. This week I present two veteran and venerable roots rock bands that came along in the second Americana wave, bands that have weathered changes and renewed their vows - Austin’s revived Uncle Lucius and Raleigh, NC-based Blake Christiana of Yarn.
