What is the best rock album of all-time?

Good god, that’s a ridiculously hard question. I’ll play it safe and say…

Pink Floyd, The Dark Side of the Moon (1973)

Dark Side, or Who’s Next

(i’d say The Beatles but too hard to pick one album)

Ted Nugent NUGENT

My nephew was forced by me to listen to ACDC’s Back in Black album when he was a child. He knows every word, not only to ACDC, but to other bands and artists as well. He grew-up, I took him to Europe, and we still ROCK!!!

Rush “All The World Is A Stage”

AC/DC “High Voltage” or “Highway to Hell”!

Iron Maiden’s “Powerslave” is a close second.

I have to pick a few, sorry

Beatles-White Album
Led Zeppelin-Four
Pink Floyd-Darkside
The Rolling Stones- Tattoo You
The Who-My Generation
Rush- Moving Pictures
Metallica- Black Album

PINK FLOYD BAYBEEEEE!! The Dark Side of the Moon!!! There is no other best.

mine will be a bit weird for you…
i don nu whether you can accept this

Daydream Nation -Sonic Youth

The Beatles – Sgt. Pepper’s Lonely Hearts Club Band
Sgt. Pepper’s Lonely Hearts Club Band is the eighth album by The Beatles. It is often cited as their magnum opus and the most influential album of all time by prominent critics and publications, ranking number 1 on Rolling Stone’s The 500 Greatest Albums of All Time in 2003. It was recorded by The Beatles over a 129-day period beginning on December 6, 1966. The album was released on June 1, 1967 in the United Kingdom and on June 3, 1967 in the United States. The album has a large influence on many artists.
Upon release the album was an immediate critical and popular sensation. Innovative in every sense, from structure to recording techniques to the cover artwork, the artistic effect was felt immediately.

There’s a lot of good answers, but I gotta go with Meatloaf: Bat Out Of Hell.

Beatles
Sgt Pepper’s lonely Hearts Club band.

Guns N Roses – Appetite for Destruction

Pink Floyd’s Dark Side of the Moon

Jimmy Hendrix, Electric Ladyland

There are lots of possible bands that are worthy of this but reading down the list of answers everyones gone for old ones and as a firm believer as just beause its new doesn’t mean its not a classic i’m going with

Muse – Origin of Symmetry

(but i might be biased)

beatles–abbey road

Elvis Costello – My Aim Is True

Led Zeppelin I

Taught the world that the blues could rock! Brought a new dimension to music.

The only one of the albums I would consider the most influential that I actually listen to on a regular basis . . .

Faith No More – Angel Dust. It was so innovative and way ahead of its time.

I have to pick a few myself
The Beatles–Revolver
Led Zeppelin–Led Zeppelin 1
Pink Floyd–Dark Side Of The Moon
Peter Frampton–Frampton Comes Alive(if “live” albums count)
Fleetwood Mac–Rumors

Appetite for Destruction- Guns N’ Roses

NIRVANA!!! all the albums rock… but i guess the album “nevermind” is the best

Well, I was gonna say Appetite for Destruction- GnR, but has already been voted for.

So I’ll go with Led Zepplin II.

The Rolling Stones – Sticky Fingers

honourable mention:
Led Zeppelin – II
AC/DC – Back In Black
The Ramones – Road to Ruin
Deep Purple – Made in Japan
