Wow, what an experience that must've been. And I appreciate that sentiment, as the Monk quote is a favorite of mine.
I agree, Neighbours is a masterpiece, along with the Ballet Adagio. It's neat to see the parallels between his work and that of the likes of the earlier artist Oskar Fischinger, and later Stan Brakhage, and I wonder to what degree these contemporaries played off each other.
You're bringing up names I haven't thought of in years. Jules Engel first showed me Fischinger's work and I was blown away.
If you haven't already seen it look for anything by Starevich, who animated insects. Or Pojar, whose work I also loved.
