One of our friends picked up this gem on ebay. To say it is rare is an understatement. Before we released our 1992 demo, Invocation of Evil, we made about 100 of these cassettes to push out to fanzines and other press ahead of the official demo release.
The cassettes, labeled "Pieper Law Review," were "liberated" from a local law school by a friend of ours who was a janitor working at that school.
Originally we had used these cassettes (about 400 of them) to make copies of our first demo, The One Dollar Demo. We had about 100 left over so we decided to use them for promotional purposes. The music on these tapes were duplicated from the cassette copy of the demo we received from Legend Studios.
