Brain Salad Surgery Had one of the coolest artwork from H.R. Giger.

court of the crimson king king crimson

Jeff Wayne’s ‘The War of the Worlds’ concept album. Marrying classic Sci-Fi and progressive rock...doesn’t get any better.

Buckingham Nicks. The only album that Lindsey Buckingham and Stevie Nicks made together before they joined Fleetwood Mac. The album was never produced as a CD except as a few poor bootlegs. I have the original album, and it's one of my favorites.

My most unusual album was/is Doctor Demento's: The Greatest Christmas Novelty CD of All Time. I love this thing. The songs are so much fun, the was a point when my kids would sing, very loudly, Christmas At Ground Zero. It's safe to say, I think it's the best album investment I've ever made.

It wasn't an album but I had a record off the back of a cereal box. I don't remember what the song was but it did play.

God Bless Tiny Tim.

The fugs greatests hits.

Ween- Pure Guava

Bitches Brew - Miles Davis. As a child it was the first album I came across (a neighbor had it) and I couldn't believe my ears when I first heard it......what a noise!!!. Of course now I have a better appreciation of the man and his music.

The best when it was released and now :Exile on Main Street

There's been a few but as far as covers go how about this.

Tyranny & Mutation by Blue Oyster Cult

Word Jazz, by Ken Nordine. 1956?

Weirdest album probably Roy Harper Come Out Fighting, Genghis Khan.

Weirdest album cover, maybe Cheap Thrills cover by R. Crumb

frank zappa joes garage not that weird an album but i bought it tripping out my face on shrooms because of the cover it spoke to me literally in the record shop

Frip & Eno, No pussyfooting

So many during 60's and 70's but for taking LSD... Moody Blues "Procession". Vinyl and Cover Art. Never a better Era, never.

Album......Tom Waits. Was a sound emersion album of no organization. My perception only.
Album cover ...... Brain Salad Surgery (concur with TristanNuvo)

For album art: Meat Loaf's Bat Out of Hell 2, the interior art is a piece that ended up being used for some small Lovecraft paperback collections, but I can't find the name of the piece at present. It's also one of my favorite albums ever.

For music...anything by Infected Mushroom really. And their album art comes in close behind Bat Out of Hell 2

Maybe the comedy albums. Had a 45 of whale songs.

Also a few of the very curious early records which were very thick. I am talking like a quarter inch thick.

Those would only play on my parents big old wood stereo cabinet because the speed was weird. 18 or something.

Somebody here will probably know.

Either Trout Mask Replica by Captain Beefheart or Yahweh or the Highway by Arab on Radar. If you check those out, kind of mentally prepare yourself.

Lenny and the Squigtones (from Leverne & Shirley fame)

Do you mean unusual artwork or music?

The strangest in musical terms I own (or have owned) has to be the Boredoms CD I bought. Its songs are seemingly random, everyday noises, from belches, farts, and clanks from the kitchen or bathroom. I don't know if I ever finished listening to it or confused noise from a neighbor's apartment with the CD, and I'm pretty sure I haven't listened to it a second time to say for certain that there's no guitar, bass, piano/keyboard, or drum playing on it, but i think that's the case. For some reason, I think I have it, which is weird because I traded in a bunch of old CDs 10-12 years ago. As far as weirdest cover art, I'll have to get back to you on that.
