Hendrix Live at Winterland. I always remember this because it was only released on CD and I didn’t own a CD player. So I bought it and copied it to a tape on my uncle’s CD player. https://en.m.wikipedia.org/wiki/Live_at_Winterland
Joe Satriani - Surfing With The Alien
don't remember what the other one was, but possibly Queensrÿche - Operation: Mindcrime
I was in tech school in the Air Force in Denver, bought a boom box with a cd player. I remember in basic training having to take a sick kid from another training flight to the hospital, since I was the only one in our flight that knew how to get there. I paid attention when we marched around Anyways, as I was waiting there in the hospital, that nurse's station was listening to a San Antonio heavy metal station (Z-Rock?) and one of the new Queensrÿche songs was played. I knew I had to get it once out of Basic Training
