The myriad threads of America’s musical tapestry are displayed: Hopi priests travel to Washington D.C. to defend their sacred snake dance; an eleven-year-old Hawaiian boy invents the steel guitar; a teenage tejana shakes the border with a ferocious feminist tango learned from a gum wrapper; the fightingest frères on the bayou turn a lament for a pretty blonde into the Cajun national anthem; and a gentle Delta farmer sings a nostalgic song of his hometown in the cold of a New York winter, and inspires the greatest rediscovery of the ’60s folk revival.
