For more than four decades now, Robin & Linda Williams have made it their mission to perform the music that they love, "a robust blend of bluegrass, folk, old-time and acoustic country that combines wryly observant lyrics with a wide-ranging melodicism." Today some might call it "Americana," but these two revered music masters were living and breathing this elixir 20 years before that label was turned into a radio format. As live performers they are second to none. Their stirring concerts have earned them a huge body of fans over the years. But as gifted songwriters Robin and Linda have earned an even rarer honor, the devotion and deep respect of their musical peers. As The Washington Post put it, "The Williamses are able to sum up a life in a few details with moving completeness." The list of artists who have covered their original songs include some of the greats of country music, names like Emmylou Harris, Tom T. Hall, George Hamilton IV, Tim & Mollie O'Brien. Robin and Linda are heard frequently on PBS' Prairie Home Companion. Local actor/songwriter/musician Willie Welch opens the show.
