Dave McGowan has written extensively on the hippie movements birth in the Laurel Canyon area of LA.
I have read his book and it is quite convincing.
There was a navy film studio in the area that had a multi-million dollar budget.
There was evidence of pedophilia and infanticide.
The rock bands that arose all had military / cia fathers and could not play their instruments.
Super interesting read and his books are available in pdf form on line.
Worth digging if you're interested.
