As glass sculptor Dale Chihuly is opening three simultaneous shows in three different venues in town, Nashville art-abouts will have the opportunity to spend the summer considering the line that separates craft from art. A similar boundary divides photojournalism from fine art photography. The barrier, however, is in no sense absolute. At its best, photojournalism can reach beyond its editorial utility and move a viewer with the power of an image alone. Visions and Voices documents the Civil Rights Movement in Nashville, commemorating the historical sit-in strikes that marked the beginning of the end of the Jim Crow era in our fair city. The exhibit offers a poignant history lesson and more than a few startling images from that turbulent time. Catch it before it closes on Saturday.
