Once outlawed and then declared Brazil's national sport in the early 20th century, capoeira, a Brazilian martial arts fight-dancing technique, originated among the country's African slave populations. In the late 1970s, Jelon Vieira founded DANCEBRAZIL (pictured), a company whose choreography marries capoeira with traditional Afro-Brazilian movement and modern dance. On Fri., JAN. 19, the acclaimed (and incredibly well-toned) group performs its swinging flips and other gravity-defying acrobatics for mouth-agape Atlantans. $32-$42. 8 p.m. Ferst Center for the Arts, 349 Ferst Drive. 404-894-9600. www.ferstcenter.gatech.edu.
