Deep in the heart of Texas, we visit with western swing trio the Hot Club of Cowtown, who started out in the bright lights of New York City and made a way to becoming a local favorite in Austin, Texas. We talk about hot clubs, 78 record collectors and hear songs about milk cows from some of the band’s favorite musicians. Then the Bay Area’s Los Cenzontles celebrate their Mexican American roots through teaching and performance, and collaborate with artists like Linda Ronstadt and Jackson Browne. It’s milk cows and mockingbirds on American Routes.
