Surprise! I decided to draw a dubstep track! hehe.
I responded to a media request from the UK Synesthesia Association, for a student who is putting together an ipad app about synesthetic experiences with electronic music. She sent me a number of very interesting tracks, and I chose to illustrate my synesthetic experience with Excision & Datsik's Deviance.
My illustration corresponds approximately to 0:26 - 0:50.
I found those heavy sounds very thick and interesting. They resonate right at the back of my jaw, at the spot where my wisdom teeth once were. I get a similar reaction from the frequencies in songs like Megadeth's Holy Wars, Down's Bury me in Smoke, Pantera's Cowboys from Hell.
On first listens, these sounds almost looked like gruyère cheese - very dense and full of air bubbles. Then I listened more closely, and could see how the sound was actually very "hairy" and layered, nuanced. The rhythmns make it very flashy and cut-apart - kind of like watching a badly animated clip.
The sound is very blue / grey (I've actually found that much electronic music has a similar color palette for me, interestingly).
So I took textured paper, layered on color pencils, scratched away the color with an opened-up paperclip, layered on color again. Then I cut the paper into strips, rubbed the edges with sandpaper and glued them onto a piece of heavy paperboard, and sandpapered everything some more.
I really enjoyed this challenge, because I don't usually listen to music like this. All I can say is, it's all about the sound!
