Rage's self-titled debut is by far their best to date, though probably for the wrong reason: "Killing in the Name." That song is great for instilling autonomy, but there were other tracks (i.e "Wake Up," "Bullet in the Head") with better messages.
That being said, Evil Empire is a great album. The first three tracks are fantasic, but don't overlook the rest of the album. Buy it for the music, keep it for the lyrics. I definitely recommend Evil Empire to all those closet libertarian socialists out there.
