the band's next release, Live in the LBC & Diamonds in the Rough, released on September 16, 2008. Its content includes live DVD from their performance at Long Beach, and a CD containing B-sides from Avenged Sevenfold, and other rarities, such as covers from Pantera's "Walk", Iron Maiden's "Flash of the Blade", and Black Sabbath's "Paranoid". Death of The Rev and Nightmare (2009–2011) In January 2009, M. Shadows confirmed that the band was writing the follow-up to their self-titled fourth album within the upcoming months. They also played at Rock on the Range, from May 16–17, 2009. On April 16, they performed a version of Guns N' Roses' "It's So Easy" onstage with Slash, at the Nokia Theater in Los Angeles. On December 28, 2009, the band's drummer James "The Rev" Sullivan was found dead at his home at the age of 28. Autopsy results were inconclusive, but on June 9, 2010, the cause of death was revealed to have been an "acute polydrug intoxication due to combined effects of Oxycodone, Oxymorphone, Diazepam/Nordiazepam and ethanol". In a statement by the band, they expressed their grief over the death of The Rev and later posted a message from Sullivan's family which expressed their gratitude to his fans for their support. The band members admitted in a number of interviews that they considered disbanding at this point in time. However, on February 17, 2010, Avenged Sevenfold stated that they had entered the studio, along with now-former Dream Theater drummer Mike Portnoy, to drum for the album, in place of The Rev. The single "Nightmare" was digitally released on May 18, 2010. The song was leaked on May 6, 2010, on Amazon.com, but was removed soon after. Mixing for the album had been completed in New York City, and Nightmare was finally released on July 27, 2010, in the United States. It met with mixed to positive reviews from music critics but was well received by the fans. Nightmare beat sales projections easily, debuting at number one on the Billboard 200 with sales of 163,000 units in its first week. After finishing recording, in December, Portnoy and the band posted simultaneous statements on their websites stating that he would not be their replacement for The Rev. However, Portnoy did travel with the band overseas in December 2010 for three shows in Iraq and Kuwait sponsored by the USO. They played for U.S. Soldiers
