Far sexier than bumping and grinding at the club, the libido-driven staccato of Argentina's two-person tango is the ultimate mating dance. On Sat., JAN. 19, Buenos Aires dance company Estampas PorteÃ±as performs "Argentina's gift to the world" in TANGO FIRE. The performance follows the tango from its start in Buenos Aires' red-light district to its current influence on ballroom dance and features company founder Carolina Soler and the music of 20th-century composer Astor Piazzolla. $39-$65. 8 p.m. Rialto Center for the Arts, 80 Forsyth St. 404-413-9849. www.rialtocenter.org.
