Okay, since this one is definitely too difficult to figure out, I'll just reveal it:
Mike Oldfield - Dark Star
What was really interesting about the process of drawing this was how the star changed from radiating darkness to radiating light and finally to radiating both. I had thought about doing this with watercolours or acrylic paint, but it turned out that charcoal was an excellent choice: There's a lot of power in this music, it's very forceful, and it requires rather a lot of force to apply that much charcoal to a white paper to make it look this dark.
I love listening to a piece of music over and over again, and transforming the sounds into an image. This is a rather unusual one, though, because colours are normally important in that process...
For those who are interested in the music: Here's the version I was listening to.
