Blues dances are a family of African-American social dances that originated from and evolved in different Black communities throughout the USA alongside the blues music styles that are typical of those areas. Although one of the oldest dances, it is still very much alive within those communities. It is a different environment than what we consider the contemporary international Blues dance scene.
Blues is not a swing dance, but there is no swing without the blues. Blues is older than swing and so are the dances danced to Blues music.
