Leviathan

Leviathan is Mastodon's 2004 concept album loosely inspired by Herman Melville's Moby-Dick, blending sludge and doom heaviness with progressive rock and metal arrangements. The record is notable for thick, down tuned riffing, shifting time signatures, layered guitar harmonies and the interplay of Brent Hinds and Troy Sanders on vocals supported by dynamic drumming from Brann Dailor. Its scope and compositional ambition helped define the band's sound and broadened their presence within progressive heavy music.
