Master of Puppets

Mezzanine

Time by the Electric Light Orchestra. that period in the late 70s and early 80s where synthesizer music was getting popular but hadn't fully codified norms yet is chock full of incredible music, and Time was one of those albums while also being the culmination of a lot of the rock and pop that came before it. add an engaging and heartbreaking story and you have a winner

It’s a tie for me

Pearl Jam. (1991). Ten [Album]. Epic Records.

A Tribe Called Quest. (1991). The Low End Theory [Album]. Jive Records.

NIИ - The Downward Spiral is the common choice, but The Fragile is a much more complete album. However, my personal favorite is Year Zero.

Either The Wall by Pink Floyd or In Rainbows by Radiohead

Or The Money Store by Death Grips

Or ænemia by Tool

Or Dirt by Alice in Chains

Or-

It's a 3 way tie between Back in Black, Led Zeppelin II and Wish You Were Here.

Paul's Boutique

Ween - Quebec
Favorite band is very tough. It’s probably Ween, and Quebec slightly over The Mollusk for me

My Arms, Your Hearse by Opeth.

Edit: tied with BURN, PIANO ISLAND BURN by The Blood Brothers.

Beatles answer: Revolver

Non-Beatles answer: Sunny Day Real Estate - the pink album

Born to Run. Wait...Darkness on the Edge of Town. Wait...Nebraska...

Kid A

Jimi Hendrix Experience's Electric Ladyland.
It's the quintessential experimental album: with songs spacing through many different genres, two 10+ minutes long jams, recurring themes and the best cover ever to be performed which is All Along the Watchtower (originally from Bob Dylan)

Somewhere Far Beyond.

They just re-recorded it and it's great.

Syro - Aphex Twin

So many synth timbers, not repetitive, and still holds a connection with dance floor nostalgia

Either <°_°> or †; have fun pronouncing them

Bleed American by Jimmy Eat World

Dream Theater "Awake" (1994). Extraordinary from the first to the last note. 75 minutes of phenomenal prog metal. They've made good and great albums before and after, but they never excelled the pure class and artistry displayed on this album.

Bruce Dickinson "The Chemical Wedding". I never liked Iron Maiden much, but Dickinson's solo stuff is a different class. Fresh, creative, varied, energetic. Most of his solo albums are well worth the listen, but "Chemical Wedding" stands out for its high variety and creativity.

Best is subjective. But my favorite album of my favorite band is Rankarumpu by Korpiklaani. I was bummed to see their previous violin player go on hiatus, but the new violinist brought a new energy to this album. Title track

Black Sabbath - Heaven and Hell

Such a refined masterpiece that few can touch. Mob rules and Dehumanizer are close seconds, but miss the sheer presence that Heaven and Hell beholds.

To me at least, Heaven and Hell is immersive and profound to an extent, that their other albums cannot compare. It holds a very special place in my heart.

Dio - The last in line.

Not quite head and shoulders above his other albums, but lands the most hits for me. I love every track on this album, and none are a "miss". I love (almost) every other Dio album, but each has at least one song that doesn't resonate with me.

Dire Straits - Brothers in Arms

Cliche choice, but extremely enjoyable to listen and relax to. If you listen more closely, it becomes very immersive as each song has a clear story and a moral. Though some tracks are slower paced and longer, I don't find a single one boring, which I sometimes do on other Dire Straits albums.

Avalon by Roxy Music.

American Idiot is better than Dookie in my opinion but apples and oranges on that.

Blackbird by Alter Bridge

prolly not a popular opinion but; violent femmes why do birds sing

Fantastic Planet by Failure

For Queen, take a listen to their second album, Queen 2. It's quite underrated, as only Seven Seas of Rhye is on the greatest hits.

However it's a phenomenal record, full of their musical experimentation that would find critical fruition in night at the opera, but a bit more raw and moody.

Black sands - bonobo

Enslaved is my favourite band and for me its a bit of a toss up between the albums 'In Times' and 'Ruun'.

Before Enslaved took the top spot, it was Dissection's 'Storm Of The Light's Bane'. Honorable mention for Opeth's 'Blackwater Park'.

Nightfall in Middle Earth

"August and everything after" Counting crows

Nonagon Infinity - King Gizzard and the Lizard Wizard. Though their other 25 albums are awesome too.

I am also partial to their album PetroDragonic Apocalypse; or, Dawn of Eternal Night: an Annihilation of Planet Earth and the Beginning of Merciless Damnation. Probably my favorite metal album, and they aren't even a pure metal band.

The Afterman: Descension

Dimension Hattross by Voivod.
