Also hadn't taken in that Gale was on Sun Ra's Lanquidity I don't think. Also Cecil Taylor's Unit Structures and Larry Young's late 60s Of Love and Peace.
I know that there was some love for at least Ghetto Music here when it was reissued a few years ago. Not heard this recording through yet but first track seems pretty reminiscent of that. The combination of spiritual jazz, folk and something operatic.
Actually when i first saw this listed i was thinking it was the far less interesting to me Eric Gale, so I had to scroll back to investigate after passing it once.
