Mastodon

An American sludge metal and alternative metal band from Atlanta, Georgia, formed in 2000 after its members — bassist/singer Troy Sanders, lead guitarist/singer Brent Hinds, rhythm guitarist Bill Kelliher, and drummer/singer Brann Dailor — met at a High on Fire concert. Known for their sludge metal with a progressive touch that remains accessible, Mastodon gained popularity with three consecutive concept albums during the 2000s. In the 2010s, the band refined its vocals and production while trying to maintain some of its previous vigor.
