Are you SURE we never met back then?
Damn, them is three great picks!

Dreams So Real - Gary Burton Quintet
Bop Til You Drop - Ry Cooder
After Bathing At Baxters - Jefferson Airplane (great performance, muddy recording, but I know when it sounds best)
Runner-up:
Also Sprach Zarathustra: Richard Strauss, Herbert von Karajan / Vienna Philharmonic, English Decca FF/FR LP.
I was wondering what you pople would consider your favorite piece of vinyl, but I think narrowing it down to just one is way too hard..

Joy Division / Unknown Pleasures
Ellington, Mingus, Roach / Money Jungle
Steve Reich / Music for 18 Musicians
Well, these types of lists are frequent fliers on AK...top 5, top 3, top 1, etc. Just to be different, I thought I'd pick the three most outrageous albums that I have. And only partially tongue-in-cheek, because I really would never part with them.
Two Sides of Leonard Nimoy is on Dot Records and has one side of the LP with him singing "Spock-ish" tunes, the other singing folk songs. It's quite horrible, but great fun if you get a kick out of things so bad that they're good.
