What is the greatest rock album of all time?

LED ZEPPELIN PHYSICAL GRAFFITTI.

1968-- Hair --as an album and as a stage production. It was a groundbreaking musical on top of, and through, social commentary. A new age, a new youth. Hair laid the path for others to follow.

Both Hair and Sgt. Pepper's Lonely Hearts Club Band were being put together at about the same time and both made their debut the latter part of 1968. As a comparison, the Beatles sound by the time of the Pepper's album was established. Hair, however, was a blast into the musical future.

Wow....only 1!!!!

hard to narrow it down that far,

I would say contenders would be:

Led Zep, IV

Def Leppard, Pyromania

Journey, Escape

Foo Fighters, colour and the shape

Pearl Jam, Ten

Boston, Boston

Van Halen, Fair Warning

Metallica, Master of Puppets

Pink Floyd, Dark side of the moon

Queensryche, Operation: Mindcrime

Rush, Moving Pictures

UFO, Lights out

I dont think I could pick 1 out of the 12

The cliche picks are going to be pink floyd, zep, etc. The greatest of all time has to be Sgt. Pepper's Lonely Hearts Club Band (1967) -The Beatles.

From the last couple decades, I would say Nirvana, nevermind.

The Who- Tommy

Journey- Escape

Led Zeppelin- Mothership

Modern:

Rise Against- The Sufferer and the Witness

Nirvana- Nevermind

I COULD GO ON & ON .

:]

The album Boston by Boston, Dream Boat Annie by Heart or ZOSO by Led Zeppelin...

I can't decide.

Nirvana-Bleach

Paranoid -Black Sabbath

Fairies Wear Boots- My favorite song.

Pink Floyd, Wish You Were Here

any led zeppelin album or dark side of the moon pink floyd.
