It's very hard to choose one best album. There are quite a few that, over the years, consistently keep me coming back and listening is satisfying from beginning to end. Some of those are:

Anathema - Distant Satellites
Avenged Sevenfold - S/T
AC/DC - Back in Black
Miles Davis - Sketches of Spain
Beck - Sea Change
David Bowie - Heathen
Bruce Dickinson - The Chemical Wedding
The Flaming Lips - Yoshimi Battles the Pink Robots
Genesis - Duke
Iron Maiden - Number of the Beast
The Killers - Sam's Town
Aimee Mann - Whatever
Mastodon - Crack the Skye
Megadeth - Countdown to Extinction
Metallica - S/T
My Chemical Romance - The Black Parade
Opeth - Watershed
Rush - Permanent Waves
Soundgarden - Badmotorfinger
System of a Down - Toxicity
Temple of the Dog - S/T
They Might be Giants - John Henry
Van Morrison - Back on Top
Roger Waters - Amused to Death
Yes - Fragile

Rumors, Fleetwood Mac
Ghost in the Machine, The Police
Stop Making Sense, Talking Heads

Nine Inch Nails- Downward Spiral
The Sisters of Mercy-Vision Thing
Massive Attack-Protection
Vivaldi-The Four Seasons
Rush-Hemispheres
Def Leopard-Hysteria

Machine Head by Deep Purple is my favorite classic hard rock album, Rocket To Russia is my favorite punk album.

The Ramones "Leave Home". Bought it at Starship Records in Tulsa in 1977 (still have it & framed). It opened a door that's never been closed.

Tori Amos fan here as well.

Pink Floyd - The Wall
Rush - Subdivisions
Alan Parsons Project - Best of

Man.... This is hard.
Danzig - Danzig I
Ghost - Opus Eponymous
Misfits - Collection 1 & 2
Neil Young - After the Gold rush
Magna Carta Cartel makes some solid tunes
... Too many to list...

The reason I cannot call myself an atheist is that I Know Tori Amos is God!

The Bends by Radiohead.

The Wall, Abbey Road, Ziggy Stardust, American Idiot

I got on the Amos bandwagon with Under The Pink, really hard to pick a favorite. Huge fan of Little Earthquakes and pretty much everything else. New to my collection and currently in heavy rotation - Schooltree (Lainey) Heterotopia, Tori Amos Native Invader, Tony Banks 5, Jethro Tull A Passion Play (deluxe version with 5.1 surround mixes), The Pineapple Thief Where We Stood, XTC Skylarking (yeah the one with Dear God), Steve Hackett The Night Siren, Steven Wilson To The Bone, Perfect Beings Vier, Hillmen The Whiskey Mountain Sessions Vol. II. Rani Chatorgoon Samsara.

The Allman Brothers Band Live at Fillmore East

Steely Dan - AJA
Deep Forest
Van Morrison and the Chieftans - Irish Heartbeat
Dead Can Dance

Well I like the classics Joni Mitchell " Blue "
Miles Davis " kind of blue "
Beatles " Abby road "
Stones " Stcky fingers "
L. Cohen " Ten new songs "
But the more obscure ones really get me
Ry Cooder " Paradise and lunch "
Country Joe MCDonald " War war war "
Pete Atkin/Clive James " A king at nightfall "

Butthole Surfers - Psychic...Powerless...Another Man's Sac
Dayglo Abortions - Feed Us A Foetus
Motorhead - On Parole
Big Daddy Meatstraw - (don't know the name of the album or if it has a name, but they bat 1000 with all their music)
and those are the ones off the top of my head that I like the full album's of (though, I like every album that Butthole Surfer's ever did)

Full album? That’s a pretty narrow list. I mean, I have a WIDE range of music I love. But as far as full on albums, I would have to say it’s a tie between:

Korn- Follow the Leader
And
Disturbed- Ten Thousand Fists

I love Little Earthquakes, and most of her other music.

LOVE it! Boys for Pele too!

Best "alt album ever":

Best "metal album" ever:

You're a big jerk. Why do you put me in this quandry? I have to break it into categories.

Daft Punk - Random Access Memories

I've seen Tori a few times. The first time was shortly after "Under the Pink" came out. I'm kinda embarrassed to say it, but it's true: I actually cried. I remember seeing all that Beatles concert footage, with all the screaming and crying girls, and thinking, "Get a life!" Well... life shoved that comment back in my face! I was there with my girlfriend, too (though she took it well and even married me... so I guess there is something to showing your sensitive side?!). Anyway... yes, Tori will always have a special place in my heart!
