Mouth of the Architect - The Ties That Blind (2006)
These guys toured with These Arms Are Snakes to support this album. It features Brent Hinds of Mastodon to do vocals on a track and the bass riffs of Brian Cook of Botch, Russian Circles, and These Arms Are Snakes. It's some pretty good sludge. Their wiki claims them to be influenced by Pelican, Cult of Luna, Isis, and Neurosis.
