Nashville singer-songwriter Kelsey Waldon is one of a handful of young artists keeping traditional country music alive and well. Signed by the late, great John Prine to his Oh Boy Records label, Waldon is revered for her nuanced, image-rich songwriting as well as her agile voice. No Regular Dog, which she recorded alongside producer Shooter Jennings (Brandi Carlile, Yelawolf), follows 2019’s White Noise / White Lines and builds upon the narrative writing and clear-eyed insight of its predecessor. Highlights include the atmospheric, fiddle-heavy “Sweet Little Girl” and the sweet, tender “Simple as Love.” But “Season’s Ending,” Waldon’s tribute to Prine, is the album’s beating heart.
