Old Crow Medicine Show is a folk/country group from Nashville, Tennessee. Along with original songs, the band performs many pre-World War II blues and folk songs. The style of music they perform is sometimes called alt-country, but today more often referred to as Americana.

They were formally inducted into the Grand Ole Opry at a special ceremony at the Grand Ole Opry House in Nashville on September 17, 2013.

Their 2004 album “O.C.M.S.” was selected by CMT (Country Music Television) as one of the top-10 bluegrass albums of that year.
