That's RAW's explanation, he comes recommended. You can get a PDF of Principia Discordia free online, I recommend the 5th edition.

The existence of that sort of person, and the circumstances that had to arise that would allow him to meet his wife at the Halloween show of a 60's era band, perturbs the imagination.  For me, the band's association with psychedelia is far less interesting than its deep connections with American and therefore human roots - Africa, Celtic (bluegrass is a blend of African and Celtic music merging in the deep southern US), Asian ("even the Buddha would agree, this song's got balance" says a recent youtube comment), and apparently Hebrew roots, according to you two - and the way this seemed to emerge as an expression of nature, rather than a forced attempt to be "multi-cultural" as would happen in these overly PC days.  "The wind bloweth where it listeth." 

Maybe the chap you mention can recommend some texts about Chassidism?
