Wot no harmonicas?

Slayer have a new album out, "Christ Illusion". On it they still "Hail Satan" and "choose 666", which is reassuring after all these years. But a closer inspection reveals that, rather worryingly, there is something serious going on here. War, religion, religious wars... that's about it as far as lyrics go, and there's no ambiguity about their position. These are hardly new concepts for metal in general and Slayer in particular, but I'd usually expect a few numbers about, I don't know, zombies in there too. There seems little doubt that this focus derives from 9/11 and all that's happened since. So not only could this be described as a concept album, this is surely... a protest album. That shreds like a bastard!
