This post is a joy because it is so packed with great listening ideas. I have several in different eras of my life but most have been listed above. When I was a child, six or seven years old, my parents took me to the movie theater to see Kubrick's 2001: A Space Odyssey. I was so enthralled by the images and music even if it didn't exactly have a narrative aimed at kids. That Christmas, in the early '70's, I received my own copy of the MGM soundtrack. I played it on our Sylvania phonograph hundreds of times; I was allowed to use the stereo from a young age. I've loved stereos and music since.

Floyd-wish you were here
Black Sabbath- sabbath bloody sabbath
Queen-Night at the opera
AC/DC-Powerage 
Stevie Ray- Texas Flood
Tull-Thick as a brick
Vanhalen- first album
Doors-LA Women
Floyd-The wall

Emy Lou Harris “Wrecking Ball”
Steely Dan “Aja”
Frank Sinatra “September of my Years”
Doors “LA Woman”
George Winston “Autumn”
MN Orchestra “ Pines of Rome”

Too many to list! However here's my entry into the world of Jazz: June 1970 I bought Bitches Brew at Woolworths! At the age of 18 I perceived it to be on a higher artistic plane than the average rock alblum! And tried to get some of my peers to listen to it!
