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) get into their electric side, and New Orleans’ own Lloyd Price shows how his R&B roots helped give birth to rock ‘n’ roll.
