The artwork

What happens below

The artwork treats a record as a slice through the earth. Mushrooms rise from its upper edge and fine threads spread beneath, connecting the visible scene to an unseen world. Music becomes the bridge: something you can feel connecting people even when you cannot see the connection itself.

Every piece funds the research behind the medicine.
