Atlanta’s Mastodon took its melodic sludge metal across the pond this past winter with Red Fang and The Dillinger Escape Plan. Along the way, it sold out London’s Brixton Academy to make it the largest UK headlining show in the band’s touring history. Catch a glimpse of the night’s action with a clip of Mastodon performing “Dry Bone Valley,” the second single off its latest release, The Hunter.
