Mastodon

Mastodon released a new album this week.  I suggest that you all go pick it up.  It has way less screaming/grunting and much more singing.  That being said I am not totally in love with it yet.  The guitars aren't as heavy this album.  It is much more prog-y than the heavy riff smack that was Leviathan or Blood Mountain.  However, the album is still great and the concept is crazy.
