I'm a big fan of concept albums, and apparently so is Mastodon. When I first saw this video, I thought they were a bunch of guys who were really in to prehistoric elephants: Mastodon, Iron Tusk. Kind of weird, but I thought the song was great. But then I picked up the album and found out is was a concept album about Moby Dick. How awesome is that?! I like everything these guys have put out, but Leviathan is still my favorite album. So rock in the weekend with Mastodon!
