You can't go anywhere on the internet without stumbling over this album...and there's a reason for that. This is Electric Wizard's heaviest album--maybe one of the heaviest albums ever made, depending on who you talk to. The guitars are super fuzzed out and tuned down and the vocals are shrouded within all of it, just the way I like it. If you haven't heard it--do yourself a huge favor and give it a listen:
Part 1
Part 2
