For Document R.E.M. picked up a much harder edge than previous albums. Sure, Life's Rich Pageant dabbled a bit with more aggressive guitar, but Document has a much harsher sound throughout. And it sounds so, so good.
Document practically kicks you in the face with the opening track, "Finest Worksong." A whip-crack snare and then Peter Buck is off to the races with an almost metal guitar intro that sets the rhythm. There's more than a little The Who influence here. And Michael Stipe's voice, once again, is crisp and clear at the forefront. This is, by the way, true to its title. If "Finest Worksong" doesn't motivate you to get shit done, seek medical care.
R.E.M. has taken on some political overtones with Document. "Welcome to the Occupation," and "Exhuming McCarthy" in particular. "Exhuming McCarthy" is also the first R.E.M. song I can recall with "found" sounds or samples, starting with the typewriter setting the tempo at the beginning, and then audio of Joseph Welch chastising Joseph McCarthy during the Army-McCarthy hearings. There's some heavy keyboard on this one, and I seem to recall it was Peter Holsapple on this track but I can't find anything today that confirms this.
