Whether done by NYC's Whitney Museum or the Atlanta Contemporary Art Center, biennials are always contentious affairs. The Contemporary's current biennial, TALENT SHOW, is no exception, delivering a mixed bag on view through Sat., AUG. 11. Some of the standouts have the two things Atlanta surely needs more of: political vitriol and humor. It's hard to know whether to chuckle or hurl over Louise Merlyn's collage collisions of celebrity culture and painful historical images. Ditto Ben Roosevelt's street-art style decals mixing the banal and the disturbing (pictured). Finally, Fahamu Pecou's video bolstering the artist's own cult of personality is, to adopt his own vernacular, "the shit." $3-$5. Tues.-Sat., 11 a.m.-5 p.m.; Thurs. 11 a.m.-8 p.m. 535 Means St. 404-688-1970. www.thecontemporary.org.
