Drawn on 80 lb. Strathmore off-white drawing paper, framed with artist's masking tape.
First I shaved graphite dust into a bowl from a graphite stick using a sandpaper block. Then I brushed the graphite dust onto the drawing paper and blotted it down - rubbing it into the tooth of the drawing paper - using a paper towel.
My drawing tools were a Pentel mechanical pencil, a Tombow Mono zero eraser pen, and various rolled paper blending stumps.
Add time plus music and...voilà
