The versions of tracks originally recorded on Fistful of Metal and Armed and Dangerous, in particular, abandon the shredding and squeals of thrash for a post-rapcore, post-grunge crunch. "Deathrider," the album's blazing opener, has been altered the most -- it used to be a headlong sprint down the stretch, but now there's a mosh-tempo break in the verses.
Here's the problem, though. The Greater of Two Evils follows a live album, Music of Mass Destruction. Anthrax's last batch of new material, 2003's We've Come for You All, was their first in five years. Is this disc fun? Absolutely. Is it necessary? Not really. The Greater of Two Evils is an entertaining effort, but Anthrax is getting a little too reliant on back catalog.
