Too subtle! lol I really like that about the Anthrax sound. You have Joey's very clean voice and then Scott with the aggression/ and Frank to maybe a little lesser degree. It's a great dichotomy! I think the only other people that have that so defined are the guitars in Megadeth both very different but together it's awesome. But I've only listened to this album twice so far. And I'd say Charlie is shining on this! And some of these riffs are really great.
Oh! and it's cool that there are two unmarked bonus tracks!
