Had a trip into Sheffield today to check out a CD/record collectors shop. Came away with Mastodon's Blood Mountain. Only played it once so far but it is another impressive album. One of the tracks on the album 'Bladecatcher' doesn't seem very popular from what I've read, but I love the craziness of it. Too soon to say which are the stand out tracks for me, although Colony of Birchmen (thought it reminded me of Queens of the Stone Age, and I see it's because Josh Homme guests on backing vocals
) and Sleeping Giant will be contenders.
