I spent way too much time on this:
I don't think the artwork was particularly special until
The Joshua Tree and
its [url=http://www.u2wanderer.org/disco/sing019.html]round of singles. The style of photography was distinct, and the way the stark desert imagery paralleled the emotional starkness of the album (not to mention its rootsy influences) was brilliant.
The Unforgettable Fire had good artwork too, just not enough of it.
Rattle and Hum also had pretty single covers (I like the "one cover per band member" idea they used with it and
The Joshua Tree).
Achtung, Baby's artwork was gritty and edgy, which fit with the music. Both did a remarkable job capturing the feel of Berlin (and the rest of Eastern Europe, really) in the early nineties, right after the wall fell. It's like everything was new again (isn't it funny that probably their most revolutionary album had a song like "Acrobat" and lyrics like, "no new ideas in the house, every book has been read"?).
Zooropa was, uh, colorful and busy. Went well with the media overload themes on the album and (moreso) the ZooTV tour.
Pop was similar, except with (obviously) a lot of retro influences. Their whole look was pretty much a gimmick during this period, but at least it looked nice. I love the cover of the
If God Will Send His Angels single.
All That You Can't Leave Behind had some brilliant artwork, though. The whole airport/bagagge/"elevation" motif was great. Anton Corbigijgjwnbwhatever's black and white photography from the Charles de Gaulle airport was beautiful. I don't think the singles were that attractive, though (I loved the cover of the "Beautiful Day" promo, an overhead shot of the boys at a beach, but they used the same pic as the album's inner sleeve for the commercial single for some reason). I'm mostly annoyed that they don't have any consistency in this department anymore; each single has a mostly different style. I was amazed (and relieved) that
The Best of 1990-2000 kept the design scheme established by
The Best of 1980-1990 given that their artwork has had multiple personality disorder for a while now.
The construction stripes and blurry photography of
How To Dismantle An Atomic Bomb was pretty slick (and I liked how they're using a serif font for everything; it's just a nice touch). I don't know how much it has to do with the album's themes, though; "Love and Peace or Else" and "Fast Cars" obviously fit. The rest of the songs seem to do with aging ("City of Blinding Lights," "Original of the Species") and God ("All Because of You," "Yahweh"). Maybe some themes about loss and such too. I think it's all a bit hodgepodge, but maybe someone else could set me straight.
