For sleepy ambient music, I record sound as I fall asleep. After I wake up, I delete all of the silence and layer up the “best bits”. I have a MicroQ set up next to my bed. I lie with my eyes closed, gradually building up a patch, my fingers feeling around the control panel, gently sending myself off to sleep.
The textures in the video were made by setting up a fractal noise generator for each of the R,G and B video channels then slowly altering noise parameters.
