"One of the great figures of American folk music, Pete Seeger, is your host for these two classic episodes from his television series Rainbow Quest, which featured interviews and performances from legendary artists of the folk tradition. Rainbow Quest: The Stanley Brothers and Doc Watson puts the focus on bluegrass, with appearances by the Stanley Brothers (featuring Ralph Stanley, who later rose to mainstream stardom with his appearance on the O Brother, Where Art Thou? soundtrack, and his brother Carter Stanley, in one of his last filmed performances), and Doc Watson, who is still regarded as one of the greatest flat-picking guitarists to ever touch a fretboard."
