Another tool that led to exposure of the band was more mainstream metal attention of Relapse Records (with acts such as Mastodon gaining popularity), as well as a full North American tour with GWAR in 2005. However, the Stop at Nothing lineup dissolved slightly in the years that followed as drummer Erik Sayenga parted yet again, and singer Vince Matthews went on to form Criminal Element. However, Dying Fetus came back yet again, bassist Beasley took over on vocals, and drummer Duane Timlin (ex-Divine Empire/Broken Hope) joined the ranks in 2006. That lineup then recorded War of Attrition, which was released in March 2007. Themes include attacking reality TV, the war on terrorism, racial ignorance, and the flaws in the criminal justice system. Songs include "Homicidal Retribution", "Raping the System", and "Parasites of Catastrophe". Dying Fetus' second music video was made for "Homicidal Retribution". Yet another lineup change occurred on the Dying Fetus front in July 2007: drummer Duane Timlin was fired due to incompatibilities. The newest drummer for the band is Trey Williams, from the local Baltimore band Severed Head. Mike Kimball also left the band and they've remained a trio since. On September 15, 2009, Dying Fetus released their sixth album, Descend into Depravity on Relapse Records. Three years later, their follow-up to this record Reign Supreme, would be released on June 19, 2012. The band released the first single from the album, "Subjected to a Beating", on April 2, 2012. Dying Fetus headlined a US tour being supported by Exhumed, Abiotic and Waking the Cadaver. Devourment was intended to be on the bill to play the tour, but dropped off a month beforehand. Rivers of Nihil appeared in select spots of the tour. On November 4, 2013, after Avenged Sevenfold were announced as a headliner for Download Festival 2014, a fan of the band claimed that other bands were more deserving of a headline spot at the festival, and said "Everyone is going on about that this is good to give new blood a chance, then why not Machine Head, Lamb of God, Testament, Dying Fetus or Carcass? Give them a chance". Due to the smaller size of the band's fanbase, this sparked a mock internet campaign with the hashtag "#WhyNotDyingFetus?" trending worldwide. On November 6, 2013, Andy Copping announced on his Twitter feed that due to the internet campaign, Dying Fetus had been confirmed to be
