Not much of a metal head, but the whole Nonagon Infinity album by King Gizzard and the Lizard Wizard is great. Also their album PetroDragonic Apocalypse.

What got me even slightly into metal, and stays mainstays on my playlists, are the albums Black Hole Space Wizard Parts 1 and 2 by Howling Giant. Cannot reccomend those enough. Also, their album The Space Between Worlds is great too, but isn’t like one long story.
