Easy to find good sounding used LPs 70s/80s.....

All of the FREE (with Paul Kossoff and Rodgers) studio albums.

Supertramp - Crime of the century

Pretty Things - Parachute

King Crimson - In the wake of poseidon

Gentle Giant - In a glass house

ELP - same (1970)

UK original presses of these sounds best, no doubt!

Little Feat - Dixie Chicken, Waiting for Columbus
The Band - Rock of Ages, Northern Lights Southern Cross, The Last Waltz
Steely Dan - Katy Lied
Bob Dylan - Blood On the Tracks, Oh Mercy
Joni Mitchell - all of hers
Bonnie Raitt - Green Light
Maria Muldaur - Waitress in a Donut Shop
Weather Report - Heavy Weather

Hard to believe THE REQUIRED ALBUM for ANY AND ALL vinyl lovers isn't listed:

Pink Floyd - Dark Side of the Moon

Yeah, OK, I guess....DSOTM is one of those records though - songs like Money, Breathe, Us & Them, Time etc...they're all kind of like "Stairway to Heaven" or "Freebird". Maybe I'm jaded, but I just don't really need to hear them again for many years to come (and there are MANY LPs that have sonics that are far superior to DSOTMs). Sorry, just one of those pet peeves.
