XII Boar, or Twelve Boar, dropped its new album Beyond The Valley Of The Triclops in August of last year, and you really ought to check it out here. The band has a pretty doom-esque sound, though it incorporates plenty of country elements to it much like early Black Sabbath.
Check out the track "Black And Blues" above, which has all the heaviness and baritone vocals you could ever want in a slow-moving track, and then grab a copy of the album right here.
