Combining acrobatic performance and the art of clowning, Cirque du Soleil returns to its roots with KOOZA, beginning Fri., JAN. 2. The electric and colorful performance leads the audience through a roller coaster journey as the protagonist, the Innocent, searches to find his place in the world while meeting a cast of comedic characters along the way. Incorporating slapstick humor with feats of strength and flexibility, Kooza seamlessly weaves fear, humor and awe, showing the world why Cirque du Soleil has kept audiences on the edge of their seats for more than 20 years. Through Feb. 22. $38.50-$195. Tues.-Thurs., 8 p.m.; Fri.-Sat., 4 and 8 p.m.; Sun., 1 and 5 p.m. Grand Chapiteau, Atlantic Station, 371 17th St. 800-678-5440. www.cirquedusoleil.com.
