This week on The New Jazz Archive, it's our salute to jazz Americana. We'll talk with Irving Berlin biographer Laurence Bergreen about the rags to riches story of one of America's greatest songwriters, and explore the role jazz musicians played in shaping the glory years of the USO. And we'll take a quintessential American roadtrip down America's Blues Highway, and chat with guitarist Bill Frisell about his search for the next great American sound.
