The sound of rock continues to dominate the musical spirit of America. Loud and anthemic, many artists eventually come to and pass through rock ‘n’ roll from country, folk, R&B, even gospel. American Routes takes a look at three roots musicians who rock: Jefferson Airplane and Hot Tuna veteran Jorma Kaukonen talks about his recent acoustic work; Texas trio The Flatlanders (Jimmie Dale Gilmore, Butch Hancock and Joe Ely) strum a few tunes in the studio; and New Orleans’ own Lloyd Price shows how his R&B roots helped give birth to rock ‘n’ roll.
