Below is a smaller excerpt of this dance description from What Dance Are You?
Sexual tension at its finest.
During the swing dance revival of the 1990s, Lindy Hop dancers took a fascination with Blues dancing, firstly because it was a slow dance that complemented their fast dancing, and secondly, it was a style that predated and contributed to the creation of their first love − Lindy Hop. Since the 1990s, swing dancers have enthusiastically taken Blues dancing worldwide, teaching and innovating on its various styles: Slow Drag, Micro Blues, Struttin’, Ballroomin’, Fish Tales, Shake ‘n Bake, Grind, Mooch, Funky Butt and Drag Blues.
Although not clearly seen at times, followers in Blues dancing emphasize delaying their movement in response to the leader’s intentions, thereby creating a constant tension with the leader in the dance. This tension symbolizes a “I’m not that easy” personality, which adds to the sexual tension and makes this dance infectious.
If you wish to learn Blues dancing, look for people who teach Lindy Hop/Swing dancing in your area as they will likely be the ones who teach Blues dance as well. They’ll probably be the people who organize social dances on a regular basis too.
