Appalachian Swing! is the second album by the American bluegrass band the Kentucky Colonels and was released on April 20, 1964 on World Pacific Records. Although it failed to chart in America, the album sold reasonably well over the course of the year and became an influential underground classic. A number of critics and authors have commented on how guitarist Clarence White's flatpicking guitar style on the album influenced the development of bluegrass guitar playing.
