LEVIATHAN

If you're looking for great sludgy, progressive metal, then Mastodon is the band for you. Leviathan is their second studio album and it is a great one too. There is a lot of screaming, jazz influenced drumming, downtuned guitars, and distorted bass, what's not to love. Songs like Blood and thunder and the long and proggy Hearts Alive are some of the best songs. There is also the addition of clean vocals, which were absent in the previous album.

If you like stoner rock, sludge metal, doom metal, progressive metal, and even more mainstream metal, you will find this album instantly enjoyable as it is very good.
