Thanks for that. I saw this a couple of years ago at a Dali exhibit, but I didn't think it was available on DVD and I've never seen it on YouTube.
It's interesting to me that someone like Dali (whose work seems so overtly psychedelic) never actually imbibed in any (at least to the best of my knowledge). And while it isn't the case with this cartoon, both Un Chien Andalou and The Persistence of Memory (two of the more enduring and recognizable pieces of "quintessential Dali" ) were actually produced prior to the invention of LSD. Likewise so many other early 20th century European artists whose work seems so off the wall even now: Picasso, The Bauhaus, the German Expressionists, Marcel Duchamp and the Dadaists - all of them pre-date LSD. So, were these white Europeans in the 20's and 30's then partaking in ayahausca? Peyote? Psilocybin? Not very likely. I'm guessing maybe absinthe at most. And what about Heironymous Bosch, way back in the 15th century? While he may not have been Alex Grey or Luke Brown, psychedelic he was.
Just goes to show that psychedelic thinking runs deeper than chemical influence...
