Those rare albums that are great on first listen.

King Crimson - "In the Court of the Crimson King"

Jethro Tull - "Thick as a Brick"

Miles Davis - "Kind of Blue"

Eberhard Weber - "The Colours of Chloë"

Pink Floyd - "Dark Side of the Moon"

There are many, many more but I also limited myself to five.  I was late to the party in discovering Miles Davis and picked up "Kind of Blue" in a record store due to the partial review on a sticker on the record.  Not having heard any Miles I took it home and played it having my mind blown.  I think I played it every day for at least a month!  "The Colours of Chloë" I heard on the radio.  I heard one amazing track and thought "I have to find out what that record is".  Then they played a different piece of music and I thought the same thing.  I wondered when they were going to tell me what they were playing.  Two more amazing pieces of music followed and then they finally gave out the play list - all four were from the same album!  You can be sure I went out and bought it immediately.

Even me who is a bit picky concur with your choices...😊

King Crimson - "In the Court of the Crimson King"

Jethro Tull - "Thick as a Brick"

Miles Davis - "Kind of Blue"

Eberhard Weber - "The Colours of Chloë"

Pink Floyd - "Dark Side of the Moon"

I could also add 

Faces Long Player

Rod Stewart Gasoline Alley

Pete Townsend Ronnie Lane Rough Mix

A little late to the party. I concur with many of the records mentioned already. Here are a few more that did it for me. There are many albums that captured me the first time I heard them, but the following still grab my attention listening with much, much better gear.

Cat Stevens: Tea for the Tillerman

Bruce Cockburn: Dancing in the Dragon’s Jaws

Cassandra Wilson: Blue Light ‘til Dawn

Lorde: Te Ao Marama (a companion piece to Solar Power. The EP is sung entirely in Te Reo Maori - remarkable)

Beyonce: act ii - perhaps the best pop album in a decade

I forgot this one...Yes...
