Schizovisionary cult radio ranter conspiracy theorist Francis E. Dec, Esquire (he insisted on the "esquire," even after having been disbarred from practicing law) was recorded by Los Angeles radio host "Doc on the ROQ" of KROQ-FM. The weirdo audio made its way around the world on cassette tape; later, fans digitized them and shared for all Kosher-Bosher mankind
The Wikipedia article on Dec is really good. WFMU appreciates his work. Here's a fan club website. Here's a Flickr set of his flyers.
Dec died in 1996. He was mentally ill. While we don't know for sure, his material suggests that he was a "machine-influencing-delusional" schizophrenic. The recordings include much racist and misogynist material: the n-word, and explicit racial hate and sexual stuff. This disclaimer applies here, too.
PS: I'm fairly certain that Gangster Computer God Worldwide Secret Containment Policy is shorthand for "Google."
