John Henry sounds as good as any TMBG effort, but on inspection, I think it also proves to be one of their deepest and most cohesive albums. Random cleverness is replaced by a subtle, consistent mood, total lyrical abstraction begins to give way to a message, and the individual songs are great. Besides, with a full twenty songs (almost an hour of music), there's bound to be something on here for everyone.
Most of the songs on Henry have a darker tone, whether explicitly (Why Must I Be Sad?; The End of the Tour) or subtly, coded into the lyrics (Destination Moon, Spy, Sleeping in the Flowers). The sound is also vaguely more _metal_ than the sort of candy-coated synthesizers and horns that characterized their earlier albums (not that there's any absence of horns), from the rough-edged harmonica opening of Subliminal to the grungy guitars on Sleeping In The Flowers and others. It may seem more commercial to some, but this sound is still entirely distinct.
As for the theme of the lyrics, it may seem hypocritical for a band which used to be more machine than man to entitle one of their albums John Henry ("a man aint nothing but a man / but before I let that steam drill beat me down / I'm gonna die with a hammer in my hand, yessir; etc.") and record a song like Thermostat, an impassioned plea against the dangers of modern automation. But the sentiment is real, and portraits of human alienation and loneliness (Spy) placed alongside villanous characterizations of machines (AKA Driver; Dirt Bike) suggest a unity which no TMBG album has had to date. The result is a deeper listening experience relying on more than puns for its effect.
As for the individual songs, the upbeat Destination Moon and James Ensor just sound terrific; some of my favorites. The End of the Tour is also powerful and genuinely touching. Some of the tracks are weaker, and I tend to skip Unrelated Thing and I Should Be Allowed to Think. Still, with this kind of quantity, the quality is very consistent.
All in all, TMBG has produced something really outstanding. Even people who dismiss them for their lack of substance (a charge that, you have to admit, is somewhat fair) should take note of Henry.
