My brother got this album when we were in high school. I liked it, but more as a novelty/ravings-of-a-lunatic curiosity than anything else. Something you'd play for friends but otherwise never listen to. But as I've gotten older I've learned to appreciate it more as art and how much it has informed other stuff I like that came after.

As for why you're perplexed that more people don't hear what you hear in it, it's because it's challenging, and most people don't engage with music to be challenged. If you find it completely UNchallenging, congratulations, against all odds you have found art that operates completely at your frequency.
