Tour break: Huntington Beach pop-punk-metal band Avenged Sevenfold is calling off its tour for a few weeks because singer M. Shadows' voice is thrashed. The band issued a statement Thursday saying that, after canceling a show Sunday in Baltimore, Shadows, a.k.a. Matt Sanders, went to his doctor and was told to rest his vocal cords for a couple of weeks. The group plans to resume touring Oct. 15 in Japan. No Southland date has been set.
