This is SO difficult. As of this morning it would go something like this, and would be diffferent again tomorrow, so in no particular order:
John Coltrane: A Love Supreme
Ravi Shankar: Live In San Francisco
Holst: Planet Suite
Pentangle: Basket Of Light
Yes: Close To The Edge
Incredible String Band: Hangman's Beautiful Daughter
The Beatles: Magical Mystery Tour US LP Version
The Kinks: Are The Village Green Preservation Society
Luxury Item: My Duvet
( I was tempted to do a Partridge and choose eight 'Best Of's' and my Ipod).
