So beyond mathematically-enthroned encryption what lies awaiting disclosure.
forgot to mention as referenced, the role of music as a form of cultural communication with potentially secret dimensions this whether classical, with entire societies networked around a given aesthetic hub or node, else within traditions themselves of various society's and the institutions these can become or the universalization of rock & roll music and the 'rock concert' as a seeming height of 20th century western popular culture, tied into mass media and media archives and vast shared communication, to include role of drug culture and consciousness and politics, including counterculture agenda, and role of trends and fashion that align with this as a form of monocultural megadevelopment who knows, perhaps those strobe and laser light displays are outputting more data, or a guitar solo is a data transmission on some other level, as carrier wave for hidden signaling. it seems for deadheads, for instance, acid may open up their experience of the music that otherwise may be intolerable and likewise maybe there are lissajous figures spinning in skulls as the result of entrainment of populations via these mind and brain-washing techniques of neurology brought into the context of mass music and its technical devices, so to program populations without their even knowing it. in this way 'communications science and engineering' may have more to do with signaling in music or as a means for programming behavior, than the music itself, if taken in a covert context. add sex, drugs, popularity and money and group-behavior and you got a platform to exploit and run against others in their own channels, (though it could tend towards baseness, bottom feeding and constitute a dumb-system by comparison to others) speculation of course. just like that wireless speaker is in no way connected to a retail dual-use spying agenda
