here's a music cult for you: "
Guitar Craft" or as it is known now "Guitar Circle"
a bit of history: in 1974 Robert Fripp had an epiphany, announces that King Crimson had "ceased to exist" ( much to the dismay of the other members as they were about to hit the big time ), and spends time at Sherborne House, which at that time was the home of J.G. Bennet's International Academy for Continuous Education, a Fourth Way organisation ( carrying on the Work, as initiated by G. I. Gurdjieff ) - this is before Bennet was sweet talked into handing over the deeds to Idries Shah ( a master con man? )
1985: Fripp starts running "guitar craft" courses, ostensibly guitar lessons, but really Gurdjieff teachings or "The Work"
Guitar Craft aimed at personal development, not only through guitar playing and music appreciation, but also through improved living. Students were offered instruction in practices such as relaxed sitting
Participants on Guitar Craft courses ( "crafties" ) are introduced to Gurdjieff concepts without the G word ever being mentioned - "conscious suffering", "self-remembering", division of attention ( left hand operating separately from the right - similar to Gurdjieff's "movements"), breaking habits ( the players have to use the New Standard Tuning invented by Fripp in order to force them to experience playing the guitar as a beginner ), objective music, and so on...
