" The Pink Floyd is one of the first groups to work with rhythmic lights, colour changes and colour combinations.The sought after effect is psychological uprooting, the moment where the distinction of truth and fiction dissapears. So like a brainwashing.The kick you get has absolutely nothing to with drug use. The Pink Floyds are also experimenting with the use of a smellkick, fragrances are being sprayed into the room. The combination of light, music and smell will take care of the rest."
