K.C. Harris is a singer-songwriter with clear roots in Americana and 1930s country blues, listing influences including Charley Patton and Blind Willie McTell. But Harris adds elements of other iconic performers, such as Bob Dylan, to forge a folk sound that pays homage to more than a century of American music.

Danny Pepper’s music is grounded in rock, grunge and country. Harris says his versatility allows him to “pair the sweetest cowboy ballad you’d ever heard with the tenaciousness of the best the early rock and rollers had to offer.”
