band, he "showed up so wasted he couldn't play." The band recorded a demo in 2000, which featured Eric Saner on vocals. Saner left the band for personal reasons after just a couple of months. After recording a four-song demo and a 7-inch picture disc through Reptilian Records, Mastodon landed a record deal with Relapse Records in 2001. Mastodon released the EP Lifesblood in 2001, and its first full-length album, Remission, in 2002, with the singles "March of the Fire Ants" and "Crusher/Destroyer" (which was also featured on Tony Hawk's Underground). On each of Mastodon's first three full-length albums, the last track was an instrumental composition with a title that related to the Elephant Man. Leviathan and Call of the Mastodon (2004–2005) The band's second full-length album, Leviathan, was released in 2004; it's a concept album loosely based on Herman Melville's novel Moby-Dick. The band received critical acclaim for Leviathan and the record was named album of the year by Kerrang! and Terrorizer. "Blood and Thunder", which featured Clutch vocalist Neil Fallon, was chosen as one of the most important recordings of the decade by National Public Radio in November 2009, and that the entire album epitomizes "a phenomenal decade for metal". Leviathan also ranked second in a list by Metal Hammer of the best albums of 2004. The band went on tour in support of the album, playing throughout North America and Europe in The Unholy Alliance tour along with Slayer and Lamb of God and later on with Slipknot. "Iron Tusk", the fifth track on the album, can be found on the soundtrack of the skateboarding video game Tony Hawk's American Wasteland and in 2K Sports video game NHL 2K9. "Blood and Thunder" is featured in the video games Need for Speed: Most Wanted, Project Gotham Racing 3 and Saints Row, as well as Japanese music games Drummania V2 and Guitarfreaks V2, and was added as a playable track on all instruments in Guitar Hero: Metallica. It has also been released as downloadable content for Rock Band 3, with Pro Guitar support also available at extra cost. Leviathan was followed by the 2006 release of Call of the Mastodon, a remastered collection of the band's first nine songs, as well as a DVD of interviews and concert footage called The Workhorse Chronicles that includes material from the band's early days as a five-piece. The band has stated that
