Raps. I've always wondered why some hippy words were ok to use at the seed and others weren't. Man, like, chick (seems very sexist). And robert seemed to get away with using even more racey or 'cool' language. I suspect this again goes back to what art considered ok. I recall art using some beatnik era lingo. He was always saying something was a gas.
But cool...that was a definite no no. Along with far-out, right-on or out of sight (this was early 70's). Music by all those mafioso, alcohol-drinking and pot smoking jazz and swing musicians was ok...because art liked it. Music by led zeppelin or pink floyd was not ok...a bunch of druggie assholes...is the way libby described led zeppelin when someone requested that a guy playing guitar in the group play stairway to heaven. I remember the guilt I felt the first time I put on some headphones and listened to Yes while an oldcomer. Listening to non-approved rock was 'rocking out'...like thinking non-approved thoughts was 'getting into your head' or philosophizing or if you questioned the inconsistency of any seed concept..you were just analyzing. All standard mind-control techniques. Thinking back on it, I'm not even sure that staff would have denied that it was all brainwashing or mindcontrol. It was too obvious. I think they just figured it was for a higher purpose...the ends justify the means.
