SAVOR THE UNCERTAINITY: If you’re above the age of 18 and don’t listen to Project 9-6-1, the annual TASTE OF CHAOS tour doesn’t mean much to you. But if you’re in that number, the following words are all that matter: Avenged Sevenfold, Atreyu, Bullet for My Valentine and Bless the Fall. The tour hits the Arena at Gwinnett Center tonight. Tickets range from $23.50 to $36.50.
