Mastodon (band) 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. The band's second full-length album, "Leviathan", was released in 2004.
Mastodon (band) 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, and 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 ""Call of the Mastodon"" is their third studio album even though the album is a compilation album. These two releases were the band's last for Relapse Records, as they would later go on to sign
