What's your favorite album cover art ?

Roger Dean

Geoffkait, I thought you were color blind.
Jasman, I agree! Anything by Neon Park which includes many Zappa albums like Weasels Rip My Flesh and Overnight Sensation. Lowell George met Neon when he was playing for Zappa. 

I like a lot of the older Blue Notes

Big Brother And The Holding Company "Cheap Thrills"

Bob Dylan and The Band "The Basement Tapes"

Google "Roy Harper Flashes from the Archives."

Hawkwind  -Space Ritual and many of their other covers like Quark, PXR5, Astounding, Hall etc.

That’s pretty ’clear’: Faust s/t on original German polydor (or later repress on recommended records).

The more I look at it, the more I love

Tears for Fears, "The Seeds of Love"

Such a snapshot of the bright and colorful late-80's/early-90's motif and so detailed in terms of symbolism and ideas!

Spirit, Twelve Dreams of Dr. Sardonicus

Me too avanti, me too.

Most Linda Ronstadt albums. 

I do like "Smell the Glove" by Spinal Tap. 

Beautifull album covers: 

1) Arbour zena (Keith Jarrett) ==> ECM 
2) Officium (Jan Garbarek & Hilliard ens.) ==> ECM 
3) Woyaya (Osibisa) 

remark: 
==> ECM record's in general have nice covers
(One of the reasons I prefer vinyl) 

Dark Side of the Moon

John Klemmer-Waterfalls

Just as an interesting aside: Did ya hear how Ahmet Ertegun, president of Atlantic Records, characterized Disraeli Gears when Cream turned in the albums tapes? Psychedelic h*rs*sh*t is what he said! Atlantic released it anyway, and consumers disagreed. 

2nd,

(The) Cream-  Disraeli Gears
The Beatles- Sgt Pepper

I have two in my collection: Cream's Disraeli Gears and Kansas self titled first album (contrary to poster above, the best Kansas album). I love the colors and clothes on the Cream cover; the photo of the band with a storm approaching is pretty awesome on Kansas' debut.  

I used the Roger Dean covers in the 70s behind an aquarium as the fit was perfect (15 gallon?), and they looked the part. Consequently all of my old Yes LPs have a little water damage on the top edges of the covers.

Mahogany Rush, Strange Universe

Country Life

Love Roger Dean, but in honor of the 45th anniversary of this album, I nominate the gatefold of the Allman Brother's "Eat a Peach".

Orleans S/T - everyone's favorite

Peter Tosh Legalise It.

Peter Tosh Legalise It.

Blind Faith/1969(I was much younger then)!

Metallica The Black Album and The Beatles White Album.

Cat Stevens "Tea For The Tillerman," Moody Blues "Every Good Boy Deserves Favour."

Stevie Wonder "Musiquarium".

Pretty much anything from KMFDM.  Artist is Aidan  Hughes

Quicksilver Messenger Service: "Happy Trails" and "It's a Beautiful Day" self titled first album.  

Mickey Katz live at the Fillmore!!

May not appeal to you aesthetically but I always loved the fake newspaper items on Thick as a Brick

Queen's "News Of The World" cover has a cool story behind it

 Queen commissioned artist Frank Kelly Freas who drew the October 1953 cover of "Astounding Science Fiction" to rework the image painting the dead band members in the robots hand.   I created my avatar with it..I always though it was an oddly interesting image.

Father John Misty "Fear Fun"
Fleetwood Mac "Mystery To Me"

Not my favorite but there's none other like it...

Mom's Apple Pie
