Rockabilly, Western Swing, jazz, blues, Tejano, Cajun, Czech — the big sounds of Texas are incredibly diverse. American Routes explores that vast terrain, visiting with Bandera, TX singer-songwriter Robert Earl Keen; Tejano accordion master Mingo Saldivar; and the King of Western Swing, Bob Wills, who is remembered by his fiddler Johnny Gimble, daughter Rosetta Wills, Bill Malone, Ray Price and Marle Haggard. Other musical Texans on tap include Illinois Jacquet, Townes van Zandt, and T-Bone Walker.
