For Avenged Sevenfold, 'Nightmare' album is part of the grief
Orange County's Avenged Sevenfold has long been known by heavy-metal fans for its riffs and its death-obsessed imagery. "Sometimes I don't know why we'd rather live than die," sang frontman M. Shadows in the band's 2005 hit "Bat Country," which topped the chart on MTV's "Total Request Live" and earned Avenged the best new artist prize at 2006's Video Music Awards.
