I grew up with Prog. I was at boarding school from the age of 10 to 15 from the late 60's to the early 70's. All of the sixth formers were really into their UK Prog records and a few stuck with me. Artists like Gentle Giant, Man, Wishbone Ash, Curved Air, Focus, Pete Brown & Piblokto, and Osibisa.
I'll upload a few of the records I grew up with.
First - Gentle Giant - Three Friends
