Mastodon's newest, "Blood Mountain" rocks my world this week. If you like your metal heavy with bold proggy meanderings (and I mean this in the best possible way), then this album is THE one you've been waiting for. I just bought it yesterday and can't get enough of it at high volume levels.
For old Mastodon fans who loved "Leviathan", you'll be pleasantly surprised. Production is very good btw..

Thought I'd share my recent discovery with my heavy metal RRers.

Cheers,

Bill
