Any effects created before 1975 were done with either tape or echo chambers or some kind of acoustic treatment. No magic black boxes!
I grew up poor and used to look at people in big houses and thought they had everything. Then, later on, I looked at models in magazines and thought they had it all. When you have the ability to live that life, to some extent you find out that they don't have any magic cure for everything.
Indubitably, magic is one of the subtlest and most difficult of the sciences and arts. There is more opportunity for errors of comprehension, judgment and practice than in any other branch of physics.
Revolutions are of no us;, it is necessary to work on transforming the brain: on sowing a different knowledge/awareness, on creating a new conscience, that is like a magic box full of brains.
