Avenged Sevenfold have announced that they won't be appearing at Australia's upcoming Soundwave Festival.  They felt they couldn't provide fans a good live show and didn't want to disappoint them.  Singer M. Shadows said in a statement, "We're really sorry it's not possible for us to play this show, and apologize for any inconvenience it has caused."  A7X plan on returning to Australia soon for their own headlining tour.
