With over half a century of hard roots-rabbling between them, Rosie Flores - the Rockabilly Filly, and Jon Langford - head Mekon, Waco Brother and conductor of the Chicago-based collective the Pine Valley Cosmonauts, blast a sonic contrail stretching from Texas to Wales, from the dusty hill country to the dusky fetter cairns. These two long-celebrated musical forces, one with her cowboy boots firmly in the dance halls and the other with his work boots sloshing around puddles of beer in the pubs, come together for an album of spirited and soulful romps through the back roads of American music.
