Capoeira
Capoeira has many theories about its foundations. One of the most quoted is that is a martial art developed by slaves which was disguised as a dance form. It is sometimes taught as a martial art today. It has evolved today into a very physical improvisational dance style including a mixture of fighting and more stylised movements often performed in a circle by two dancers who try and outwit each other with thier movements. It take lots of control, focus and concentration.
