Appalachian music has also influenced a number of musicians from outside the region. In 1957, British skiffle artist Lonnie Donegan reached the top of the U.K. charts with his version of the Appalachian folk song "Cumberland Gap," and the following year the Kingston Trio had a number one hit on the U.S. charts with their rendition of the North Carolina ballad, "Tom Dooley". Grateful Dead member Jerry Garcia frequently performed Appalachian songs such as "Shady Grove" and "Wind and Rain", and claimed to have learned the clawhammer banjo style from "listening to Clarence Ashley". Bob Dylan, who also performed a number of Appalachian folk songs, considered Roscoe Holcomb to be "one of the best," and guitarist Eric Clapton considered Holcomb a "favorite" country musician. Classical composers Lamar Stringfield and Kurt Weill have used Appalachian folk music in their compositions, and the region was the setting for Aaron Copland's "Appalachian Spring". In the early 21st century, the motion picture "O Brother, Where Art Thou?", and to a lesser extent "Songcatcher" and "Cold Mountain", generated renewed mainstream interest in traditional Appalachian music.
