I'm sure you've seen the New Age "revival"
that's been going on for awhile now. that big compilation on Light In the Attic that came out like 7 or 8 years ago.
unlike a lotta things that get dug up and revived, New Age has always had a commercially successfully niche. it was just the antithesis of cool.
it's not just about smoothness, it was also uncool in the nerdy prog sense. Jean-Michel Jarre, Kitaro, all the terrible Berlin School synth music.
even the dug up stuff is, in my opinion, mostly terrible. as a good rule of thumb, the later you go in time - toward the later 80s - the worse it's likely to be.
some of the later Popol Vuh stuff is alright, but Florian Fricke was always kind of just his own thing
