I think you meant to say you like album covers designed by The Designer's Republic.
Did you realise all those covers were designed by the same people? Actually, maybe the Squarepusher one isn't.
The cover of 'Amber' is really fucking beautiful... I was sitting on the IDM mailing list at the time it came out and someone said the photo is off some mountains near their house, in Utah!? And 'Tri Repetae' is great "in the flesh", the way it's different bits of card, rather than a booklet, so it can be rearranged to make different covers. Oh wait, I think you chose 'Anvil Vapre'. Oh well.
Actually, another, very different cover that does a similar rearrangeable thing to 'Tri Repetae' is Pulp's 'Different Class'. That's bloody tasty.
And sorry to Kai, but I really fucking hate King Crimson's album covers. If not for Genesis they'd be up for some big time YOU'RE SHIT award for most consistently bad album covers. Maybe 'Starless and Bible Black' was OK? Their 90s comeback rubbish was bloody ugly.
As well as the Touch stuff I mentioned above, I really like Old Dirty Bastard's
Return to the 36 Chambers and also
Zammuto's 'Willscher'.
