although the format was orignally a Presley cover, this in my book is one of the greatest album covers of all-time. Like they say, a picture can tell a thousand words...
I don't think I can post this, but Suger Ray's Lemonade and Brownies is by far my favorite album cover. http://www.mikecade.com/media/sexy_album_brownies_lemonade_sugarray.jpg
Ben Folds Five - Naked Baby Photos inside cover: Pretty much any KISS album before 1980, here's my favorite:
Yeah, that was from before Sugar Ray became a bunch of flamers. That's Nicole Eggert btw. Man, what happened to her?
It wasn't really a cover, since there was no insert and the front was just clear. As a result, this was what was printed on the CD itself, which kind of became the cover. One of the more clever ones, I've always felt.
Great call! Especially the "Country Life" one which is probably NSFW I also like this one for some reason: The Cars' first album is another that comes to mind.
I'm not sure it's safe so I won't post it... Black Crowes - Amorica (before the cover was censored for your protection)
Spinal Tap is such an amazing movie. I can't tell you how many Spinal Tap parties I've had with my friends... This one creeps me out whenever it pops up on itunes...
More of my favorites are the Yes albums from the 70's. The artwork was done by Roger Dean and can be seen and purchased here... http://www.rogerdean.com/upclose/yellowcity.htm
