If the track listing for this album looks familiar, it's probably because you own Mastodon's out-of-print "Lifesblood" EP. Some fans probably think that re-releasing this EP is a way of the band cashing in on their popularity; but personally, I think it's just a way of Mastodon providing this C.D. to their fans without making them pay a billion dollars for it. Plus, "Call of the Mastodon" also features four extra early songs ("Thank You For This," "Deep Sea Creature," "Slickleg," and the title track) which are extremely hard to find.
Every Mastodon characteristic is in place on this album: bouncy, walloping drums, big, bone crunching riffs, and throaty vocals. But this album is also somewhat different from "Remission" and "Leviathan," because it sounds quite a bit more raw and thrashier. A couple of movie samples are also slipped into the mix here and there.
The album begins with "Shadows that Move," which has explosive, churning riffs. The next track, "Welcoming War," has pounding guitars and insanely fast drumming. "Thank You For This" is backed by buzzsaw guitar flurries, and "We Built This Come Death" jumps from being slow and restrained to an almost blindingly fast tempo. Track six, "Battle At Sea," is probably my personal favorite. It begins slowly, but it eventually kicks into high gear (with a blast beat, lumbering riffs, and Deicide-esque bellows).
"Call of the Mastodon" may only be 29 minutes long, but it's essential for every complete Mastodon collection. As another reviewer said, you will find a lot to like here (if you're already a Mastodon fan), so, if you need to, you should sell your copy of "Lifesblood" to have enough money to buy this C.D.
