I wonder if his tone is always this passive agressive :D
Psydub is what the crusty hippies listen to when they get tired of dancing. Or when the drugs wear off. Or when they choose horse tranquilizers instead of LSD.
Every scene has its chill room genre and Psy Dub arrived pretty quickly after Goa Trance established itself, with intentions to offset the busy acid lines, doofing drumkicks, and screaming melodies with something lowkey and non-expressive. Every artist album has one or two ballad songs for Prom season. In Psy Trance's case those songs were Psydub.
It has changed a lot over the years. An early name for it was Psybient (which is still in use for any Psydub that has no Dub in it), and it was a Psy Trance take on the emerging Chill Out sounds of Ambient House (ie: The KLF, The Orb and the like) -- simple breakbeats with mutant acid lines but slowed down so they're less squiggly wiggly and more squirmy whirmy. These are technical terms.
As Psydub is a different trip than other Psy Trance genres, it attracts a certain class of person: The cerebral hippie, who holds vast quantities of knowledge about life, biology, mathematics, quantum physics, computer programming, cosmology, human history, evolution, and whatever the hell Deepak Chopra is babbling about, except that half of it is bullshit and all of it is wrong.
Never get your science education from paranoid burnouts who think human evolution was seeded by black-eyed extraterrestrials who have recently returned only to slaughter cattle and probe our buttholes (although to be fair the data contained within our buttholes has the potential to advance galactic science by many years).
I like Psydub!
