Kind of Blue, of course, back in the good old days of vinyl. Circa 1977/78. It was quite the rage among my circle of friends (theater-artsies, dancers, band geeks, freaks....) back in those highschool days.
My parents had Sketches of Spain, which was often played early in the evening when they held parties, so I kind of grew up with Miles. My dad also had ESP, but I don't recall it ever being played.
