Led Zeppelin Houses of the Holy LP. It was 1979 and my parents bought me a Fisher combo with a record player, a tape deck and some small speakers of some unknown origin. It wasn't much but it was all they could afford at the time and I was extremely grateful. My father did not buy anything for himself and he was also very much into music. So even then I knew a sacrifice was made.
I remember my first small record collection well. I had a dozen or so records and mostly Led Zeppelin, Pink Floyd, Meat Loaf and AC/DC. I really did not know much American music outside of rock, pop and disco back when I was barely a teenager.
I got into the Blues and Jazz later in my 20's
