Sorry, Bonnewagon, I don't find them, more like they find me................😃
B-W, In terms of absolute productivity, I don't think any kind of whole earth catalogue of just exactly what is out there even exists . Most of this stuff came and went in a very brief amount of time, around 6 years to be more or less precise.
The parameters for it were 1966-1972, which is not a coincidence.
That brief era was a battleground for a lot of things. Generation fought generation for freedom of thought and word. Music waged war with itself over what was socially appropriate and morally acceptable. The military sought to suppress ideology that it considered subversive or defeatist. Religions decried the actions and attitudes of the masses as morally bankrupt and blasphemous from the pulpit. And internal unrest and social upheaval were rampant on many fronts.
The most confusing thing about music in the psychedelic era was how fleeting and ephemeral and transient it all really was. Musicians came together, created small bodies of work, cut records, and broke up again; kind of like one of those french court ball room dances pre revolution. The comments for several of the groups that I screened last night made a point of mentioning how many groups some of the players had been in. A substantial number of records were actually one hit wonders with no album or followup to bolster them.
The other point is that the Vietnam era, which directly overlaps most of the psychedelic era, played a large part in determining what music got air time and what got suppressed. The military considered contemporary music to be suspicious to the point of being subversive and went out of its way to restrict access to it by the troops and censor what did get allowed on the Military Radio,, Total tongue in cheek, but Robin Williams and "Good Morning, Vietnam" did address the issue from a semi-humorous perspective.
Just as a counterpoint to all this, as of right now, almost half or more of the total count of logged and catalogued urls in my Favorites Folder are for music. My MMPITA, Most Monumental Pain in the ***, is that Edge insists on dumping my catalogue folders because it wants to know what I am listening to so it can "guide" me.
And of course stuff disappears because property rights get violated and then the admin steps in and pulls the link.
Plus which, of course, my taste in music is mostly in my tongue🤣
So, as I happen to come across them, and if they happen to appeal to me, then who knows what might show up as a url/link?
