As an elementary school kid I heard Slave's "The Concept" being played by a classmates older brother. I asked my parents for the cassette tape for Christmas. I believe that was 1978. I still own that cassette tape. I played it through middle school, high school, and college. Got some strange looks in college from people and many "what are you playing?" When I bought my first new car after graduation it was the first tape to be played as I drove off the lot.
I bought a VPI turntable in 1996. The Concept was one of the first vinyl albums I had to play on my latest audio purchase. I own at least 7 copies of the album and enjoy it as much today as I did the first time I heard it playing. The big deal for me is to hear it through all tubes- phono, pre, and power.
