Did a search, and no one's really talking about these guys, and people should be.
Saw them open for Tool last night, and their set blew me away almost as much as Tool's did. They just wandered onto stage and tuned up their instruments, said "Hi", then put out one of the most cohesive and engaging sets I've seen a band put on in a while. Very much music to groove out to rather than get pumped up and mosh, but it's really cool stuff. Their drummer, especially, is really excellent. Musically, it's a little like a bastard child of Mastadon and Opeth. If you get a chance to see them live, do it.

Funny, I listened before reading your post, and Mastodon came to mind very early on. Not so much Opeth, though. I thought they sounded like Mastodon meets Between The Buried And Me.
Not so impressed by the drummer judging from those clips. It's very meat and potatoes style playing. Hit or don't hit. Not much dynamic playing. But he's clearly very proficient and capable. Don't wanna hate on him too much.
But that's pretty cool stuff, man. I think I could dig an album of this. Sounds like the kind of stuff that can be devoured as an album, not just the odd song here and there.
