This week on American Routes, we dip into crossover currents of country music sung by Black American performers, including Ray Charles, Ike and Tina Turner, and Fats Domino. We’ll also hear white musicians influenced by Black music: Bob Wills and the Texas Playboys, Jimmie Rodgers and Bob Dylan. Then, it’s the Baton Rouge Blues legacy, with recordings from Buddy Guy, Slim Harpo, Silas Hogan, Tabby Thomas and the late harmonica man Raful Neal. Plus a live performance from Raful Neal’s son, Kenny Neal, a mouth harp and guitar player, now the senior statesman and artist from the Baton Rouge Blues scene.
