Album number six from Mastodon continues their path towards a more proggy rock sound with a few twists and turns. There still isn't any screaming to be found but compared to their last album, 'Hunter', it's a wee bit heavier musically. I think their tour with Alice In Chains and the Deftones left a mark on them as little bits of both can be found here and there. Overall a very strong addition to their resume.
