Mastodon Summits Blood Mountain

Atlanta's Mastodon is set to unleash Blood Mountain, its follow-up to the acclaimed Leviathan, sometime this summer. In an interview with MTV from April (yeah, we're kind of behind), the group mentioned members of Neurosis and The Mars Volta appear on the album. A fan recently posted a video of an unamed song on YouTube, if you'd like a preview. The footage was captured on a recent New Jersey date of The Unholy Alliance Tour, which will feature Mastodon until July 26th.
