A reception Saturday, March 15, at Chattanooga's Graffiti gallery, 505 Cherokee Blvd., will kick off a one-week show by the art collective Art Nomad, a group of four senior photography students at the Savannah College of Art and Design in Atlanta. April Bell, Caitlin Sciscoe, Jordan Bailey and Le Le Leseur, from left, will attend the opening of "Symbiosis," which showcases each individual photographer's point of view, rather than a single theme. The reception is set for 5 to 10 p.m. The exhibit closes Saturday, March 22. For more information, all 423-400-9797 or visit www.hillcityart.com.
