In my record and CD library, Frank Zappa has his own shelving unit--I've lost track of how many recordings I have, and there are some that I haven't listened to yet.
My first exposure to Zappa was when I was maybe about 12--my local library had a record room where you could take an LP off the shelf and listen to it in a private listening room. I had found 'Over-Nite Sensation' and the album art looked interesting, so I put it on---and didn't really know what to make of it until I got to 'Montana'--after that, I had to find out who this guy was. When I got into high school, I made friends with a vibe player in the jazz program who was a Zappa fanatic and had all of his material up to that point. We would sit around and smoke we.......er, ah,.....think pure thoughts and have marathon Zappa parties. Good times.
