I left out my classical side and only took the top ten of what truly influenced me as I heard 9 out of 10 of these when they were released and very much formed my musical preferences.  

Not only albums, but WNEW FM in New York early 70’s with Alison Steele (the night bird). She was a big Moody Blues fan.  
She introduced me to On the Threshold of a dream. That shaped my listening and inspired me to look for bands with orchestra backing.  Some others...
Time Out Take Five - Dave Brubeck
Sargent Peppers - and early stuff from the Beatles
2001 Movie soundtrack really introduced me to classical music. 

al jarreau - we got by/glow
michael franks - art of tea
crusaders - southern comfort
coltrane - my favorite things
miles davis - sketches of spain
dire straits
mingus - tijuana moods
kenny burrell - guitar forms

Thanks Mapman, you're damn right about “Machine Head” by Deep Purple followed by “Demons and Wizards” by Uriah Heep. How could we forget?And one more, Black Sabbath's first. My Catholic neighbor bought it and was so afraid his parents would find out we waited a week before we could listen to his on his dad's high end system. Blew our minds...He's since become a musician, and has worked with Jon Anderson (YES).
