Mastodon is a Grammy Award-nominated heavy metal band from Atlanta, Georgia. They are one of the most notable bands in the New Wave of American Heavy Metal.They were formed in 1999 by Troy Sanders, Brent Hinds, Bill Kelliher, Brann Dailor and original vocalist Eric Saner. They have released four full-length albums and have toured worldwide, achieving increased album sales and an ever expanding fan base with each new release.
Mastodon was formed in late 1999 when drummer Brann Dailor and guitarist Bill Kelliher moved to Atlanta from Rochester, NY and met bassist/singer Troy Sanders and guitarist/singer Brent Hinds at a High on Fire show. They discovered they had a mutual appreciation of sludge metal bands Melvins and Neurosis and '70s hard-rockers Thin Lizzy, and shortly thereafter formed Mastodon. In an interview in 2009, Kelliher revealed that the first time Hinds attended a practice with the band, he "showed up so wasted he couldn't play".
They recorded a demo in 2000, which featured the band's first lead singer, 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.They released an EP, Lifesblood in 2001 and their first full-length album, Remission, was released in 2002, with the singles "March of the Fire Ants." and "Crusher/Destroyer" (which was also featured on Tony Hawk's Underground) On the first three of Mastodon's full-length albums, the last track of each relates to the Elephant Man. - Wikipedia
