Mastodon has been touring around Europe with Neurosis vocalist Scott Kelly performing all six songs he's guested on. If you're not aware, those songs are "Scorpion Breath," "Aqua Dementia," "Crack The Skye," "Diamond In The Witch House," "Crystal Skull" and "Blood And Thunder."
Mastodon played all six in that exact order at Blondies in London for a Kerrang! video, and you can watch the whole set above. By the way, when are we getting that new Mastodon song? The only rumor floating around right now is that it's called "Fallen Torches," which isn't much to go on.
