That is the subject of the present poem "Dust", which deals with this very motif. The poem itself began as a request from a close friend, Samantha Monteleone, who asked that I assist her in constructing the lyrics to a song. She said that the only line she had was "my dust" and proposed the tempo sound like footsteps. So, I worked my craft, and churned out this curious specimen. She has since incorporated it into a brilliant work-in-progress, making it very much her own. I myself experimented with sounds and produced a different version. I'm going to try and post that version up somehow, but in the meantime please enjoy these "lyrics".
The dust of what has come before
UPDATE: Samantha has since completed her song and uploaded it to YouTube. She has entitled it "only just Dust". I personally think it's quite brilliant, and highly suggest you Like it and leave feedback for her in the Comments.
