Avenged Sevenfold's last release was the DVD/CD package, "Live in the Lbc & Diamonds in the Rough", which came out in September 2008. The live DVD features the band's April 2008 hometown show at the Long Beach Arena headlining the Rockstar Taste of Chaos tour, while the CD contains previously unreleased b-sides that were recorded during the making of "Avenged Sevenfold", plus various covers, and other never-before-heard material. The DVD was directed by Core Entertainment's Rafa Alcantara, who also worked on the band's critically acclaimed 2007 road documentary "All Excess".
