I'm also interested in musicians, and how their creativity has been affected by psychedelic experiences.
In terms of Music, the melodies I come up with are 1:1 with the audio hallucinations I have. They may not sound exactly the same (perhaps a trippy sound that I'd have to synthesize), but the melodiies, harmonies, and rhythms are exactly the same. Luckily, music benefits
greatly from tripping. I can't forget those ideas because I can play or sing the ideas as they're happening.
Tripping changes your musical ideas the same way it changes your thought patterns. Everything becomes novel, simple but perfect new ideas come to you with ease. You find it so easy to create and create and create.
You are also way more spontaneous, BUT! You spontaneity always seems to hit the right notes. It's so amazing. You can make a mistake and turn it into a great sounding song. If you were sober, that mistake wouldn't have gone anywhere.
If you have any musician friends who trip, please ask them if you can hang around the next time they plan to trip and make music. You'll love it.
I think that except perhaps in special cases, any artist who is communicating an experience through their art is going to end up communicating more than a single experience... more like the essence of psychedelia to them at that time combined with an individual experience. It's not like all the psychedelic art out there is 100% what you saw during a trip... I'm sure Alex Gray for example doesn't take acid and see exactly what he paints. But what he has gotten from the psychedelic experience, he expresses through his paintings.
I know when I write about experiences, more ends up coming out than just the simple relating of thought processes and visions during that experience. It ends up being a complete product of all of the psychedelic experience I've had thus far in life, a building up of a concept based on a bunch of different smaller experiences. It's based on a single trip and it's telling that story, but the art that comes out contains more than just that.
Now back to visuals: Alex Grey is a perfect example. He might not make these exactly, but he does such a great job of expressing the idea of "psychedelic" that I was convinced he had eidectic memory. Which is a possibility for some of these visionary art works (I would like to believe).
But it seems as if psychedelics change your sense of aesthetics and that whatever you draw has an authentic psychedelic feel if you want it to. Like, if an artist had never seen a Picasso cubist painting or Dali's melting clocks, but that artist happened to be very skilled, they could immediately make some very inspired Cubist / Surrealist paintings from a short impression. Is that what you mean? It's pretty much the same thing for CEVs/OEVs?
As an aside, I've always wanted to write psychedelic poetry but words have failed me. You can write endlessly about what you've experienced, but you can't make the words themselves psychedelic. Unless you did some kind of psychedelic kinetic typography, which is kind of like cheating.
However, psychedelics have inspired me not to create music, but to merely bring out the music within me. I've dabbled in everything from black metal to acoustic to trip hop to drone to doom to post rock to ambient.
