Old Crow Medicine Show is an Americana string band based in Nashville, Tennessee. Its music has been called old-time, folk, and alt-country. Along with original songs, the band performs many pre-World War II blues and folk songs. It has recorded since 1998. Bluegrass musician Doc Watson discovered it while its members were busking outside a pharmacy in Boone, North Carolina in 2000. With an old-time string sound fueled by punk rock energy, it has influenced acts like Mumford & Sons and contributed to a revival of banjo-picking string bands playing Americana music—leading to variations on it.
