Who is releasing this?
I hope it's a better...curated presentation than this: https://www.dustygroove.com/item/939151?sf=avant+garde&incl_oos=1&incl_cs=1&kwfilter=avant+garde&sort_order=artist
It's a good frame to put around this music, which was, in its own ways, as much relevant to "the culture" as was the pop music it was inspiring. Pop artists tend to have aspirations more than deep skills, so this stuff is a well upon which to draw. Not a knock on the aspirational but less skilled, quite the opposite, their willingness to go there keeps the flow going, and of course, what goes around comes around.
I do hope this is a good and thoughtful presentation and not some PD mishmash with liners that name drop with out illumination. If it is, hey, count me in, a good compilation is a nifty thing to have around!
