Greatest albums of all time, or
favorite albums? There's a difference.
I'd have to define "great" as being an album that changed the direction of the genre it represented, or became a groundbreaking statement. or made such an impact on the music industry that it's still being felt 25 or 30 or 40 years later. It would have to have stood the test of time, and be relevant even today.
The #1 album in THAT regard then, would have to be
Meet the Beatles.
Say what you will about Presley or Cash or the Stones, but MTB
STARTED rock and roll for 99% of the people who heard it.
My second choice would also have to be a Beatle LP - Sgt Pepper - those of you too young to have been growing up when this album was released have NO concept of the impact it had in 1967. Take Born To Run, add in Thriller, and top off with DSOM and you have some idea. Everything else since then is just 'another rock album'. And I say this admitting that I'm not even a big Beatles fan.
Third? Johnny Cash's Folsom Prison live album. Took C/W away from Flatt and Scruggs and gave it back to the realists.
Fourth? Dylan's Highway 61 Revisited. - did for "folk" what Cash did for C/W. Totally changed the entire genre. After that, The Kingston Trio were never the same again...
Fifth? Considering the impact it had on millions of guitarists for whom it may have been the first "non-pop" rock album, you'd have to give the nod to Cream's "Wheels of Fire". Again, it took rock and roll in a whole new direction.
"Thriller" probably has to be in the list there somewhere - it ushered in the era of sexy teenybopper favorites from Madonna to Spears to Lil Kim and the rest. Virtually ALL solo "pop" artists of today owe it to Jackson for getting them started.
Born to Run? Yeah, it was a watershed.
Jimi Hendrix's first album blew nearly everything else on the charts completely out of the water. Totally unique. Never heard anything like it, and never will.
Grunge? Rap? Hip-Hop? Not familiar enough to say with any authority. Get back to me in 30 years and we'll see.
And I'll admit that apart from Hendrix and Cream, I don't own any of the other one's I listed.
