Music/pop-culture guru Simon Reynolds claims
that industrial music (in the original Throbbing Gristle/Cabaret Voltaire sense, not the gothic-teen-angst-techno-metal sense seen today) was
the second flowering of an authentic psychedelia (authentic as opposed to retro; see also: Dee-Lite, Lenny Kravitz, Sophie Lee and the Freaked-Out Flower Children), and the harsh, Dadaistic aesthetic was in some ways a direct progression from the psychedelic rock and acid happenings of the 1960s.

Hmm. I wonder how much this has to do with the trance DJs who are still apparently hanging out at outdoor fests. Including roots'n'blues ones.
