A speaker faces the wall about one meter away from it, emitting a sound clip i had made in 2017 during a residency in Badamera, northern Madagascar. The sound waves from this speaker bounce off the wall and can be heard on the other side of the gallery almost just as loudly as they can be heard at this speaker, creating an ambiguous sonic displacement for the voice within the track. On the wall that this speaker faces is another speaker facing back. The wires of this speaker are taped onto the wall, connecting to lines of chalk drawing. The sound is silent. But the mural is noisy. Together, the two speakers form a connected signal, a heterodyne, that links the visual marking in the mural into a sonic sensibility.
